Isolated MOSFET Driver

Features

General Description

The Supertex HT0440 is a dual, high voltage, isolated

MOSFET driver utilizing Supertex’s proprietary HVCMOS^®

technology. It is designed to drive discrete MOSFETs

conﬁgured as bidirectional or unidirectional switches. It

can drive N-channel MOSFETs as high-side switches up to

400V. The HT0440 generates two independent DC isolated

voltages to the outputs, V_OUTA and V_OUTB when logic inputs A

and B are at logic high.

► ±400V input to output isolation

► ±700V isolation between outputs

► No external voltage supply required

► Dual isolated output drivers

► Option of internal or external clock

Applications

► Telecommunications

► Modems

The internal clock of the HT0440 can be disabled by

applying an external clock signal to the CLK pin. This allows

the power dissipation and AC characteristics to be tailored

to meet speciﬁc needs. The CLK pin should be connected

to ground when not in use. The HT0440 does not require

any external power supplies, the internal supply voltage is

supplied by either of the two logic inputs, A or B, when they

are at logic high.

► Solid state relays

► High side switches

► High end audio switches

► Avionics

► ATE

For detailed circuit application information, please refer

to application note AN-D26.
