Supertex inc. HT0440 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. в–єв–є В±400V input to output isolation
в–єв–є В±700V isolation between outputs
в–єв–є No external voltage supply required
в–єв–є Dual isolated output drivers

в–єв–є Solid state relays
в–єв–є High side switches
в–єв–є High end audio switches
в–єв–є Avionics
в–єв–є ATE 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 …
