General Description

The HT0740 is a single-channel high-voltage low input

technology. It is designed to drive discrete MOSFETs

configured as high-side switches up to 400V. The

HT0740 generates an independent DC-isolated

is at a logic high. The HT0740 does not require any

external power supplies. The internal supply voltage is

provided by the logic input when it is in high state.
