VOM1271

The VOM1271 from Vishay Dale is a stand-alone, optically isolated MOSFET driver designed for high-integration solutions. It draws all necessary current for its internal circuitry directly from the LED current on the low-voltage primary side, eliminating the need for external power supplies. This component integrates a rapid turn-off circuit, enhancing switching speed by reducing turn-off time.

Key electrical specifications include an open-circuit voltage of 8.4 V typical at 10 mA forward current and a short-circuit current of 15 μA typical at 10 mA forward current. The isolation test voltage is rated at 3750 VRMS, ensuring robust isolation for various applications. The input is logic compatible, making integration into existing designs straightforward.

Packaged in a small SOP-4 surface-mount form factor, the VOM1271 offers a small footprint. Its applications include high-side drivers, solid-state relays, floating power supplies, power control, data acquisition, and ATE systems. Agency approvals include UL, cUL, VDE, and FIMKO, indicating broad compliance and reliability.

This device is supplied on tape and reel, suitable for automated assembly processes. Its design focuses on saving space and cost for engineers developing isolated gate driver solutions.
