HT0740

High Voltage Isolated MOSFET Driver

Ordering Information

General Description

The Supertex 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 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.

Features

❏ ±400V input to output isolation

❏ No external voltage supply required

❏ Low input logic current, 500µA max

❏ Floating isolated output

❏ 5.0V logic compatible

Applications

❏ Telecommunications

❏ Modems

❏ Solid state relays

❏ High side switches

❏ High end audio switches

❏ Avionics

❏ ATE
