General Description
The Supertex HT0440 is a dual high voltage isolated driver
utilizing Supertex’s proprietary HVCMOS® technology. It is de-
signed to drive discrete MOSFETs configured as bi-directional or
unidirectional switches. It can drive N-channel MOSFETs as high
side switches up to 400V. The HT04 generates two independent
DC isolated voltages to the outputs, VOUTA and VOUTB when logic
inputs A and B are at logic high. The internal clock of the HT04 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 HT04 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.
