Description
The ISL83202 is a medium-frequency H-Bridge FET driver with a peak drive current of 1A (typ) that is intended for driving high- and low-side N-Channel MOSFETs in medium-voltage applications. The ISL83202, which is optimized for PWM motor control and uninterruptible power supply systems, offers simple and flexible bridge-based design. The ISL83202 is excellent for switching frequencies up to 200kHz, with typical input-to-output propagation delays as low as 25ns and a user-programmable dead-time range of 0.1s to 4.5s. The ISL83202's dead-time can be programmed using a single resistor. The ISL83202's four separate driver control inputs (ALI, AHI, BLI, and BHI) allow driving of any switch combination except those that would result in a shoot-through condition.
