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.
