General Description
The Supertex HT0740 is a single channel, high voltage, low input current, isolated driver utilizing Supertex’s proprietary HVCMOS® technology. It is designed to drive discrete MOSFETs, configured as high side switches, up to 400V. The HT0740 generates an independent DC isolated voltage across the pair of outputs when the logic input is at a logic high. The HT0740 does not require any external power supplies.
