THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENTARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT MOSFET Driver with Integrated Fast Turn-Off , Solid-State RelayADDITIONAL RESOURCESDESCRIPTIONThe 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.

2 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 Driver Open circuit voltage at IF = 10 mA, V typical Short circuit current at IF = 10 mA, 15 A typical Isolation test voltage 3750 VRMS Logic compatible input High reliability Integrated rapid Turn-Off circuitry Material categorization: for definitions of compliance please see High-side Driver Solid-state relays Floating power supply power control Data acquisition ATE isolated solenoid drivers isolated high current relay drivers isolated high voltage relay driversAGENCY APPROVALS UL cUL VDE FIMKO Note For additional information on the available options refer to option information.

Though these parts are generally capable of supplying higher output current, they lack Integrated fast Turn-Off circuitry.

8 Thus, if high Turn-Off speed is required. external circuitry needs to be provided, as illustrated in Fig. 10 illustrates the ability to do away with external Turn-Off circuitry with the VOM1271, by taking advantage of the VOM1271 s Integrated Turn-Off circuitry.
