Dual, High Voltage,
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, VOUTA and VOUTB 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.

Absolute Maximum Ratings are those values beyond which damage to the device may occur.
Functional operation under these conditions is not implied. Continuous operation of the device
at the absolute rating level may affect device reliability. All voltages are referenced to device
ground.
