Applications
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, confi gured 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. The internal supply voltage is supplied from the logic input when it is in the high state.
