LVT8216S-TA1-V-G Application in U.S. SAE J1772 EV Chargers
As electric vehicle adoption continues to expand in the United States, AC EV chargers are becoming an important part of residential, workplace, commercial, public and fleet charging infrastructure.
A typical U.S. Level 2 EV charger operates from a 208/240 Vac supply and commonly uses the SAE J1772 Type 1 charging interface. In addition to the high-power charging path, an EV charger requires low-voltage control circuits to manage switching, status signals, protection functions and communication between the control electronics and the power stage.
This is where LVT8216S-TA1-V-G can be considered for isolated control and switching applications.
The publicly available LITEON LTV-8216S-TA1 product is identified by major electronic component distributors as aMOSFET-output optocoupler / PhotoMOS relay with a 1-Form-A configuration. Because the exact suffixLVT8216S-TA1-V-Gshould be verified against the current manufacturer documentation, engineers should confirm the complete ordering code and electrical specifications before production use.
For EV charger designers, this type of optically isolated switching component can be useful when a low-voltage controller needs to control or isolate a signal associated with another electrical domain.
LVT8216S-TA1-V-G in U.S. EV Charger Applications
A U.S. AC EV charger typically contains several functional blocks, including AC input protection, power switching, charging control, communication and user-interface functions.
The control architecture can be separated from the high-voltage power section.
A simplified control path can be described as:
EVSE Controller → Isolated Control Interface → LTV-8216S-TA1 Family → Relay or Contactor Driver → Charging Power Control
The exact circuit topology depends on the EVSE design and the electrical characteristics of the selected component.
The isolation boundary is particularly important because the control electronics and power section can operate at substantially different electrical potentials.
An optocoupler or PhotoMOS-type device can provide an isolated interface between these domains.
Why Electrical Isolation Matters in an EV Charger
Unlike many low-voltage consumer electronics products, an AC EV charger is directly connected to the vehicle charging power system.
A U.S. Level 2 EVSE can operate from a 208/240 Vac supply, while the control electronics may operate at much lower voltages.
LITEON's U.S. EV charging portfolio includes products designed for 208/240 Vac operation and SAE J1772 Type 1 charging. Its IC 80A platform, for example, supports up to 80 A and incorporates connected-EVSE functions such as Ethernet, Wi-Fi, 4G LTE and OCPP.
This electrical environment makes isolation an important part of EVSE architecture.
The control board may contain:
MCU or EVSE controller
Communication interface
Wi-Fi or Ethernet
4G LTE
RFID
Display interface
Energy metering
Fault monitoring
Relay or contactor control
Pilot signal processing
Power management
These functions do not necessarily operate in the same electrical domain.
Isolation helps separate low-voltage control circuitry from circuits associated with higher voltage or potentially hazardous electrical conditions.
How an Optocoupler Can Be Used in an EV Charger
An optocoupler transfers a control signal through an optical interface rather than through a direct electrical connection.
A simplified signal path consists of:
MCU Output → Optical Input → Isolation Barrier → MOSFET Output → External Control Circuit
This architecture allows the controller to command a switching function while maintaining galvanic isolation between the input and output sides.
In an EV charger, such an isolated switching interface may be considered for functions including:
Relay control
Contactor interface
Auxiliary power switching
Isolated status signaling
Power-stage control
Protection-related control paths
The actual application must be validated against the electrical ratings and switching characteristics of the exact LITEON ordering code.
LVT8216S-TA1-V-G and EV Charger Relay Control
One potential application is controlling an auxiliary relay or providing an isolated interface to a contactor driver.
An EVSE controller normally cannot drive a high-power relay or contactor directly from an MCU GPIO.
A typical architecture may therefore use:
MCU → Optical Isolation → Switching Interface → Relay or Contactor Driver → Main Power Contactor
This approach provides separation between the low-voltage controller and the switching circuit.
Separation Between Control and Power Circuits
The low-voltage MCU side can remain electrically isolated from the output switching domain.
Reduced Direct Electrical Coupling
The optical interface limits direct electrical interaction between different circuit domains.
Flexible Control Architecture
The controller can generate a relatively low-power control signal while the isolated output interfaces with an external switching circuit.
Additional System Protection
Isolation can help limit the direct propagation of certain electrical disturbances or faults between circuit domains.
The isolation component itself does not constitute a complete EVSE safety system. Appropriate circuit protection, insulation, creepage, clearance, grounding and certified protective components are still required.
U.S. EV Charger Architecture: SAE J1772 Type 1
The U.S. EV charging market has its own connector and system requirements.
A common AC charging configuration uses the SAE J1772 Type 1 interface.
LITEON's U.S. AC charging products include 208/240 Vac input and SAE J1772 Type 1 charging interfaces. Its IC 80A platform is specified for up to 80 A and supports connected-EVSE functions including Ethernet, Wi-Fi, 4G LTE, OCPP 1.6J, OCPP 2.0.1 and ISO 15118 Plug & Charge.
This illustrates how a modern EV charger has evolved beyond a simple power relay.
A connected EVSE can combine:
Power + Control + Isolation + Communication + Authentication + Safety
As a result, isolation and interface components are important parts of the overall electronic architecture.
Where LVT8216S-TA1-V-G Fits in the EVSE Control System
An EV charger can be divided into several functional areas.
1. AC Input and Protection
This section manages incoming AC power and associated protection functions.
2. Power Switching
Contactors, relays and other power components control the actual charging power path.
3. Control and Communication
The MCU or EVSE controller manages charging authorization, pilot signaling, fault handling, user interfaces and network communication.
4. Isolation and Interface
Optocouplers and PhotoMOS-type components can provide electrical separation between different circuit domains.
When its verified electrical specifications match the application,LVT8216S-TA1-V-G / LTV-8216S-TA1 can be evaluated within this fourth functional area.
It should not be automatically regarded as the main high-current charging switch.
Why PhotoMOS and MOSFET-Output Optocouplers Can Be Useful
The LITEON LTV-8216S-TA1 is categorized by major distributors as a MOSFET-output optocoupler / 1-Form-A PhotoMOS relay.
Compared with a conventional mechanical relay, a PhotoMOS architecture provides a solid-state switching interface.
Potential advantages in selected EVSE control circuits include:
No mechanical contact wear
Silent switching
Compact PCB integration
Optical isolation
Solid-state output
Suitable for low-level control and switching functions
However, the device should not automatically be treated as a replacement for the main EV charging contactor.
The main charging path involves significantly higher power and safety requirements. The appropriate contactor, relay or switching technology must be selected according to the EVSE's voltage, current, fault conditions, certification and system architecture.
LVT8216S-TA1-V-G Is Not the Main EV Charging Switch
This distinction is important for EV charger engineers and purchasing teams.
A U.S. Level 2 EV charger may operate from 208/240 Vac and deliver substantial current to an electric vehicle.
The main charging current is normally handled by appropriately rated power components such as:
Contactors
Power relays
Circuit breakers
Solid-state power devices
Protection components
An optically isolated MOSFET-output device is better understood as a control, interface or auxiliary switching component when its electrical specifications meet the application requirements.
Therefore, the engineering role should generally be considered as:
LVT8216S-TA1-V-G → Control / Isolation / Auxiliary Switching
rather than:
LVT8216S-TA1-V-G → Main EV Charging Power Switch
This distinction is particularly important when developing a safe and compliant U.S. EVSE.
EV Charger Control Example
Consider a connected Level 2 EV charger.
When an electric vehicle is connected, the EVSE controller evaluates the charging conditions and determines whether the power path can be enabled.
A simplified sequence is:
EV Connected
The controller verifies the required charging conditions.
Control Command
The MCU or EVSE controller generates the required switching signal.
Isolation Interface
The signal passes through an isolated control interface.
Contactor Driver
The isolated output controls the relay or contactor driver.
Power Connection
The main charging contactor closes when all required conditions are satisfied.
Charging
AC power is supplied to the vehicle through the charging interface.
If a fault is detected, the controller can remove the charging command and initiate the appropriate shutdown sequence.
The exact implementation depends on the EVSE hardware architecture and applicable safety requirements.
Isolation and EVSE Fault Protection
EV chargers must be designed to handle abnormal operating conditions.
Potential events include:
Overcurrent
Ground fault
Leakage current
Overvoltage
Undervoltage
Overtemperature
Communication failure
Contactor failure
Pilot signal abnormality
Internal control-board fault
An isolation component can be part of the signal architecture that separates the controller from another monitoring or switching circuit.
For example:
Fault Detection Circuit → Isolation Interface → EVSE Controller
or:
EVSE Controller → Isolation Interface → Contactor Driver
The purpose is to establish a controlled interface between electrical domains.
The isolation component alone does not provide complete EVSE safety. It must be integrated with the complete protection and control architecture.
LITEON EV Charging Experience
LITEON has extensive experience in EV charging systems and states that its EVSE products have been deployed in European and American markets
since 2013.Its EV charging portfolio includes AC and DC charging systems and portable charging solutions.
LITEON's current U.S. AC charging solutions include features such as:
208/240 Vac input
SAE J1772 Type 1
Up to 80 A for the IC 80A platform
Ethernet
Wi-Fi
4G LTE
OCPP 1.6J / 2.0.1
ISO 15118 Plug & Charge
NEMA 4 protection
IK10 impact resistance
This broader EVSE experience provides useful context when evaluating LITEON electronic components for charging-system designs.
LVT8216S-TA1-V-G for Smart and Connected EVSE
Modern U.S. EV chargers increasingly combine charging functionality with connectivity.
A connected EVSE may incorporate:
EV Charger + Wi-Fi + Ethernet + 4G LTE + Cloud Platform + OCPP + RFID + Charging Control
LITEON's IC 80A platform, for example, supports Ethernet, Wi-Fi, 4G LTE and OCPP 1.6J/OCPP 2.0.1.
As the number of electronic subsystems increases, clearly defined electrical domains and reliable interface circuits become increasingly important.
An optically isolated switching component can therefore be considered for selected EVSE control interfaces where its electrical specifications are appropriate.
U.S. EV Charger Compliance Considerations
A component used in an EV charger cannot be selected solely according to nominal voltage or current.
The complete EVSE must meet the applicable requirements for the intended market and application.
Depending on the product architecture and target market, U.S. EVSE designs may involve requirements associated with standards such as UL 2231
and UL 2594.
LITEON's U.S. EV charging products also identify additional market-specific certifications and compliance features for certain applications.
When evaluating LVT8216S-TA1-V-G or the verified LTV-8216S-TA1 part, engineers should consider:
Isolation requirements
Working voltage
Switching voltage
Switching current
Temperature
Creepage and clearance
PCB layout
Insulation system
Surge and transient environment
Applicable EVSE standards
Final product certification
The latest manufacturer datasheet and qualification documentation should be checked against the actual EVSE design before production approval.
