General Description

The Supertex HT07 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 HT07 generates an independent DC isolated voltage across the pair of outputs when the logic input is at a logic high. The HT07 does not require any external power supplies. The internal supply voltage is supplied from the logic input when it is in the high state.
