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
AGENCY APPROVALSfeatures, 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
