The 33984 is a dual self-protected 4.0 mOhm 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. Programming， control， and diagnostics are implemented via the serial peripheral interface （SPI）。 A dedicated parallel input is available for alternate and pulse-width modulation （PWM） control of each output. SPI-programmable fault trip thresholds allow the device to be adjusted for optimal performance in the application. The 33984 is packaged in a power-enhanced 12 mm x 12 mm nonleaded PQFN package with exposed tabs.
