Description
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.
