Dual Intelligent High-current Self-protected Silicon High Side Switch (4.0 mΩ)

The 33984 is a dual self-protected 4.0 mΩ silicon switch used to replace electromechanical relays, fuses, and discrete devices in power management applications. The 33984 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

• Dual 4.0 mΩ max high side switch with parallel input or SPI control

• 6.0 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, under-voltage and over-voltage shutdown, fail-safe

pin status, and program status

• Enhanced -16 V reverse polarity VPWR protection
