Vishay Optically Isolated MOSFET Drivers
Vishay Optically Isolated MOSFET Drivers provide the voltage required to drive the gate of a low-voltage MOSFET. The gate voltage is generated by photovoltaic cells, and no power supply is needed on the output side. This simplifies designs when using low-voltage MOSFETS. The single channel VOM1271T provides 8.4 V output voltage with an input forward current of just 10mA. The dual channel VO1263AACTR provides 14.5V output voltage.
