Technical Data  
Single Intelligent High-current  
Self-protected Silicon High Side  
Switch (2.0 mΩ)  
33982B/C  
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 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 the output.  
SPI programmable fault trip thresholds allow the device to be adjusted  
for optimal performance in the application.  
Bottom View  
The 33982 is packaged in a power-enhanced 12 x 12 nonleaded  
PQFN package with exposed tabs.
