Vishay Intertechnology Automotive Grade Photovoltaic MOSFET Driver Options Built-in Flip-Off Circuit in Compact SOP-4 Package deal

MALVERN, Pa. — June 7, 2023 — Vishay Intertechnology, Inc. (NYSE: VSH) right now launched a brand new Automotive Grade photovoltaic MOSFET driver that's the first such gadget to supply an built-in turn-off circuit within the space-saving SOP-4 bundle. Designed to ship excessive efficiency for automotive functions — whereas growing design flexibility and decreasing prices — the Vishay Semiconductors VOMDA1271 options the trade’s quickest switching occasions and highest open circuit output voltage.

The built-in turn-off circuit of the optocoupler launched right now permits a turn-off time of 0.7 ms typical, which is the quickest for a MOSFET driver within the compact SOP-4 footprint. As well as, the VOMDA1271 supplies a turn-on time of 0.05 ms — twice as quick as competing gadgets — and is the one driver on this bundle dimension to supply an isolation voltage of 3750 V and a typical open circuit output voltage of 8.5 V, which permits it to drive a wide range of MOSFETs.

The AEC-Q102 certified gadget is meant to be used in pre-charge circuits, wall chargers, and battery administration methods (BMS) for electrical (EV) and hybrid electrical (HEV) autos. To generate the upper voltages wanted to drive IGBTs and SiC MOSFETs in these functions, two VOMDA1271 optocouplers can be utilized in collection. As well as, the driving force permits designers to create customized solid-state relays to interchange legacy electromechanical relays in next-generation autos.

The optically remoted VOMDA1271 options an AIGaAs infrared LED (IRLED), which emits gentle that's absorbed by a photovoltaic gate array, producing the voltage used to activate a MOSFET. This building simplifies designs and lowers prices by eliminating the necessity for an exterior energy provide. For even larger design flexibility, the gadget will be pushed by a microcontroller’s GPIO pin. The optocoupler is RoHS-compliant, halogen-free, and Vishay Inexperienced.

Samples and manufacturing portions of the VOMDA1271 can be found now, with lead occasions of eight weeks.
