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 inde-

pendent 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.
