Advance 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 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 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
