Description
The IRSF3031 is a three-terminal monolithic SMART POWER MOS FET with built-in short circuit, over-temperature, ESD and over-voltage protections and dual set/reset threshold input.
The on-chip protection circuit latches off the power MOSFET in case the drain current exceeds 4A (typical) or the junction temperature exceeds 165°C (typical) and keeps it off until the input is driven below the Reset Threshold voltage. The drain-to-source voltage is actively clamped at 55V (typical) prior to the avalanche of the power MOSFET, thus improving its performance during turn-off with inductive loads.
The input requirements are very low (100µA typical) which makes the IRSF3031 compatible with most existing designs based on standard power MOSFETs.

Features
■ Extremely Rugged for Harsh Operating Environments
■ Over Temperature Protection
■ Over Current Protection
■ Active Drain-to-Source Clamp
■ ESD Protection
■ Compatible with Standard Power MOSFET
■ Low Operating Input Current
■ Monolithic Construction
■ Dual Set/Reset Threshold Input

Applications
■ Solenoid Driver
■ DC Motor Driver
