ce Information  
Single Intelligent High-current  
Self-protected High-side Switch  
(2.0 mOhm)  
34982  
The 34982 is a self-protected 2.0 mOhm high-side switch replacing  
electromechanical relays, fuses, and discrete devices in power management  
applications. The 34982 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.  
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.  
The 34982 is packaged in a power-enhanced 12 x 12 mm nonleaded PQFN  
package with exposed tabs and powered by SMARTMOS technology.

• Single 2.0 mmax. 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 overcurrent limit, overcurrent fault blanking time, output OFF  
open load detection, output ON/OFF control, watchdog timeout, slew-  
rates, and fault status reporting  
• SPI status reporting of overcurrent, open and shorted loads,  
overtemperature shutdown, undervoltage and overvoltage shutdown, Fail-  
safe pin status, and program status  
16-PIN PQFN  
Applications  
• Low-voltage factory automation  
• DC motor or solenoid
