The Supertex HT0440 is a dual, high voltage, isolated MOSFET driver utilizing Supertex’s proprietary HVCMOS® technology. It is designed to drive discrete MOSFETs configured as bidirectional or unidirectional switches. It can drive N-channel MOSFETs as high-side switches up to 400V. The HT0440 generates two independent DC isolated voltages to the outputs, VOUTA and VOUTB when logic inputs A and B are at logic high.
