HT0440

Dual High-Voltage Isolated MOSFET Driver

Features

General Description

• ±400V Input to Output Isolation

• ±700V Isolation between Outputs

• No External Voltage Supply Required

• Dual Isolated Output Drivers

HT0440 is a dual high-voltage isolated MOSFET driver

that uses HVCMOS technology. It is designed to drive

discrete MOSFETs configured as bidirectional or

unidirectional switches. In addition, it can drive

N-channel MOSFETs as high-side switches up to 400V.

The HT0440 generates two independent DC-isolated

voltages to the outputs V_OUTA and V_OUTB when logic

inputs A and B are at logic high.

• Internal and External Clock Options

Applications

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 customized 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 provided by either of the

two logic inputs, A or B, when these inputs are at logic

high.
