DESCRIPTION
The VOMDA1271 is an automotive qualified optically
isolated MOSFET driver. The VOMDA1271 obtains all the
required current to drive its internal circuitry from the
infrared emitter on the low voltage, primary side of the
isolation barrier. No power supply is needed to provide VCC.
The VOMDA1271 features a turn-off circuit to achieve a fast
turn off of the MOSFET.
