VOMDA1271T Automotive Photovoltaic MOSFET Driver

Vishay's MOSFET driver delivers gate voltage up to 8.5 V with only 10 mA input current

Image of Vishay Semi Opto's VOMDA1271T Automotive Photovoltaic MOSFET DriverVishay's VOMDA1271T MOSFET driver features an infrared emitter that emits light which is absorbed by a photovoltaic gate array which generates the voltage used to turn on a MOSFET. The VOMDA1271T simplifies designs and lowers costs by eliminating the need for an external power supply for the MOSFETs.

The device can be driven by a microcontroller’s GPIO pin. To generate the higher voltages needed to drive IGBTs and SiC MOSFETs, two VOMDA1271T optocouplers can be used in a series. In addition, the driver enables designers to create custom solid-state relays to replace legacy electromechanical relays in next-generation vehicles, increasing reliability, lowering costs, and saving space.
