Photovoltaic driver streamlines EV power designs
A photovoltaic MOSFET driver from Vishay, the VODA1275 increases safety and reliability in high-voltage automotive applications. The device provides a typical open-circuit voltage of 20 V, short-circuit current of 20 µA, and turn-on time of 80 µs—said to be three times faster than competing devices.
The AEC-Q102-qualified device targets pre-charge circuits, wall chargers, and battery management systems for EVs and HEVs. Its high open-circuit output voltage allows a single driver to be used, removing the need for two devices in series to generate higher voltages. The VODA1275 also enables custom solid-state relays to replace electromechanical relays in next-generation vehicles.
A working isolation voltage of 1260 Vpeak and isolation test voltage of 5300 VRMS make the driver well-suited for 800-V+ battery systems. The device comes in a compact SMD-4 package with an 8-mm creepage distance and a mold compound with a CTI of 600.
Samples and production quantities of the VODA1275 are available now, with lead times of eight weeks.
