The 33982 is a self-protected silicon 2.0 mΩ high side switch used to replace electromechanical relays, fuses, and discrete devices in power management applications. The 33982 is designed for harsh environments, and it includes self-recovery features. The device is suitable for loads with high inrush current, as well as motors and all types of resistive and inductive loads.

Features
• Single 2.0 mΩ max high side switch with parallel input or SPI control
• 6.0 V to 27 V operating voltage with standby currents < 5.0 μA
• Output current monitoring with two SPI-selectable current ratios
• SPI control of over-current limit, over-current fault blanking time, output-OFF open load detection, output ON/OFF control, watchdog timeout, slew rates, and fault status reporting
• SPI status reporting of over-current, open and shorted loads, over-temperature shutdown, under-voltage and over-voltage shutdown, fail-safe pin status, and program status
• Enhanced -16 V reverse polarity VPWR protection
