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 HT0440 generates two indepen-
dent DC isolated voltages to the outputs, V
OUTA
and V
OUTB
when
logic inputs A and B are at logic high. 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 character-
istics 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.
