The 33982 is a self-protected silicon 2.0 m

 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.

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 the output. 
SPI-programmable fault trip thresholds allow the device to be adjusted 
for optimal performance in the application.

The 33982 is packaged in a power-enhanced 12 x 12 mm 

nonleaded PQFN package with exposed tabs.

• Single 2.0 m

 max high side switch with parallel input or SPI 

control 

• 6.0 V to 27 V operating voltage with standby currents < 5.0 

A

• 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 V
