Intersil ISL83202IPZ

Полумост48,5 В ~ 15 В

Overview

The ISL83202IPZ 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 medium voltage applications. Optimized for PWM motor control and uninterruptible power supply systems, the ISL83202IPZ enables simple and flexible bridge-based design. With typical input-to-output propagation delays as low as 25ns and with a user programmable dead-time range of 0.1µs to 4.5µs, the ISL83202IPZ is ideal for switching frequencies up to 200kHz. The dead-time of the ISL83202IPZ 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 ISL83202IPZ to refresh the bootstrap capacitor when pulled low. Integrated undervoltage protection and shoot-through protection ensure reliable system operation. The ISL83202IPZ is available in compact 16 Ld SOIC and 16 Ld PDIP packages and operates over the range of -55°C to +125°C.
