Photovoltaic MOSFET Driver with Integrated Fast Turn-Off, Solid-State Relay FEATURES
• Open circuit voltage at IF = 10 mA, 8.4 V typical • Short circuit current at IF = 10 mA, 15 μA typical 1 4 • Isolation test voltage 4500 VRMS Turn • Logic compatible input Off • High reliability 2 3 • Integrated rapid turn-off circuitry • Material categorization: i179066_6 For definitions of compliance please see www.vishay.com/doc?99912
APPLICATIONS DESCRIPTION
• High-side driver The VOM1271 is a stand-alone optically isolated MOSFET • Solid-state relays driver. Unlike conventional MOSFET drivers, which require • Floating power supply an external power supply to provide VCC and or VDD rails to the driver itself, the VOM1271 obtains all the required • Power control current to drive its internal circuitry from the LED current on • Data acquisition the low voltage primary side of the isolation barrier. This • ATE saves the designer the space and cost associated with • Isolated solenoid drivers providing one or more external power supplies. The VOM1271 also integrates a turn-off circuit internal to the • Isolated high current relay drivers component itself, thus doing away with the need for • Isolated high voltage relay drivers 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 The safety application model number covering all products designers with a small footprint, highly integrated isolated in this datasheet is VOM1271. This model number should be gate driver solution for a large variety of MOSFET drive used when consulting safety agency documents. applications. • UL1577 • cUL, equivalent to CSA bulletin 5A • FIMKO EN 60950-1
