Single Intelligent High-current Self-protected High Side Switch (2.0 mOhm)

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 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.

特性 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
