Product Usage
The TLP350H optocoupler is commonly used in a variety of circuits to provide electrical isolation between high-voltage and low-voltage components. This device is particularly well-suited for applications involving the control of power devices like IGBTs (Insulated Gate Bipolar Transistors) and MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors). Below are some typical circuits and applications that might use the TLP350H:
The TLP350H is frequently used in gate driver circuits for IGBTs and MOSFETs. It provides isolation and drives the gate of the power switch, enabling efficient control in power electronics systems.
The TLP350H is used in motor control circuits to drive transistors that control the motor phases.
In switching power supplies, the TLP350H may be employed to isolate control signals from the high-voltage output circuits.
The TLP350H can be used in industrial automation systems to drive high-power components while isolating the control electronics from potentially hazardous voltages.
In battery management systems (BMS) for electric vehicles or energy storage systems, the TLP350H can drive switches or relays that connect or disconnect battery cells.
Here’s a simplified example of a gate driver circuit using a TLP350H to drive an IGBT or MOSFET.
