The VOM1272 is a stand-alone optically isolated MOSFET driver, now packaged in a mold compound with a comparative tracking index (CTI) of 600, enhancing insulation performance. The VOM1272 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 VOM1272 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 SOP-4 package, provide designers with a small footprint, highly integrated isolated gate driver solution for a large variety of MOSFET driver applications.
