Vishay Semiconductors Photovoltaic MOSFET Driver with Integrated Fast Turn-Off, Solid-State Relay FEATURES • Open circuit voltage at IF = 10 mA, 8.4 V typical 1 • Short circuit current at IF = 10 mA, 15 μA typical • Isolation test voltage 4500 VRMS • Logic compatible input • High reliability • Integrated rapid turn-off circuitry • Material categorization: For definitions of compliance please see www.vishay.com/doc?99912 APPLICATIONS • High-side driver • Solid-state relays The VOM1271 is a stand-alone optically isolated MOSFET driver. Unlike conventional MOSFET drivers, which require an external power supply to provide VCC and or VDD rails to the driver itself, the VOM1271 obtains all the required current to drive its internal circuitry from the LED current on the low voltage primary side of the isolation barrier. This saves the designer the space and cost associated with providing one or more external power supplies. The VOM1271 also integrates a turn-off circuit internal to the component itself, thus doing away with the need for additional components in order to increase the overall switching speed by decreasing the turn-off time. These features, combined with a small SOP4 package, provide designers with a small footprint, highly integrated isolated gate driver solution for a large variety of MOSFET drive applications. • Floating power supply • Power control • Data acquisition • ATE • Isolated solenoid drivers • Isolated high current relay drivers • Isolated high voltage relay drivers AGENCY APPROVALS • UL1577 • cUL, equivalent to CSA bulletin 5A • FIMKO EN 60950-1 SAFETY AGENCY COMPLIANCE Please see document: www.vishay.com/doc?83743 Note • For additional information on the available options refer to option information.

Vishay Semiconductors ISC - Short Circuit Output Current (μA) VOC - Open Circuit Output Voltage (V) Fig. 6 - LED Reverse Current vs. Reverse Voltage Fig. 8 - Short Circuit Output Current vs. Open Circuit Output Voltage IF (mA) Fig. 7 - LED Forward Voltage vs. LED Forward Current APPLICATION DESCRIPTION Figure 8 illustrates a standard isolated MOSFET driver such as Vishay’s VO1263. Though these parts are generally capable of supplying higher output current, they lack integrated fast turn-off circuitry. Thus, if high turn-off speed is required. external circuitry needs to be provided, as...
