Freescale Semiconductor  
Technical Data  
Dual Intelligent High-current  
Self-protected Silicon High Side  
Switch (4.0 mOhm)  
33984  
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.  
HIGH SIDE SWITCH  
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 x 12 mm  
nonleaded PQFN package with exposed tabs.

Features  
• Dual 4.0 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, under-voltage and over-voltage shutdown, fail-safe  
pin status, and program status
