ISL6440 Overview
Key Features
- An adjustable overcurrent protection circuit monitors the output current by sensing the voltage drop across the lower MOSFET
- Hiccup mode overcurrent operation protects the DC/DC components from damage during output overload/short circuit conditions
- Each PWM has an independent logic-level shutdown input (SD1 and SD2)
- A single PGOOD signal is issued when soft-start is complete on both PWM controllers and their outputs are within 10% of the set point
