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. • Solid-state relays • Floating power supply • Power control • Data acquisition • ATE • Isolated solenoid drivers • Isolated high current relay drivers • Isolated high voltage relay drivers AGENCY APPROVALS The safety application model number covering all products in this datasheet is VOM1271.

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 illustrated in figure one. Figure 9 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. 2 MΩ Channel 1 control + – P-channel JFET Switch 1 N-channel MOSFETs Fig. 9 - Typical MOSFET Driver Application without Integrated Fast Turn-Off Rev. 1.6, 07-Jan-14 Document Number: 83469 4 For technical questions, contact: [email protected] THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE.
