Vishay's New MOSFET Driver Addresses EV Power System Complexity
Event summary
- Vishay introduced the VODA1275, an Automotive Grade photovoltaic MOSFET driver in a compact SMD-4 package.
- The VODA1275 features a 8 mm creepage distance and CTI of 600, a first for this package size.
- The device offers a turn-on time of 80 μs, three times faster than competing devices, and supports 800 V+ battery systems.
- The driver simplifies designs by eliminating the need for two drivers in series, reducing space and cost.
- Samples and production quantities are available now with an eight-week lead time.
The big picture
The introduction of the VODA1275 highlights the ongoing trend towards increased voltage levels (800V+) in electric vehicle battery systems to enable faster charging and increased range. This component addresses a key design challenge – managing high voltages with smaller, more efficient components – and positions Vishay to capitalize on the growing demand for advanced semiconductor solutions in the automotive sector. The device's ability to replace two drivers with one represents a tangible cost saving for OEMs, a critical factor in the price-sensitive EV market.
