General Description

Features

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

unidirectionalswitches. ItcandriveN-channelMOSFETsashigh

side switches up to 400V. The HT0440 generates two indepen-

dent DC isolated voltages to the outputs, V_OUTAand V_OUTBwhen

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.
