The ISL83202 is a medium-frequency H-Bridge FET driver

capable of 1A (typ) of peak drive current that is designed to

drive high- and low-side N-Channel MOSFETs in mediumvoltage applications. Optimized for PWM motor control and

uninterruptible power supply systems, the ISL83202 enables

simple and flexible bridge-based design. With typical inputto-output propagation delays as low as 25ns and with a userprogrammable dead-time range of 0.1µs to 4.5µs, the

ISL83202 is ideal for switching frequencies up to 200kHz.

The dead-time of the ISL83202 is programmable via a single

resistor. The ISL83202's four independent driver control

inputs (ALI, AHI, BLI, and BHI) allow driving of every

possible switch combination except those that would cause

a shoot-through condition. A global disable input, DIS,

overrides input control and causes the ISL83202 to refresh

the bootstrap capacitor when pulled low. Integrated

undervoltage protection and shoot-through protection ensure

reliable system operation.

The ISL83202 is available in compact 16 Ld SOIC and 16 Ld

PDIP packages and operates over the range of -55°C to

+125°C.
