Advance Information

Dual Intelligent High-current

Self-protected Silicon High-side

Switch (4.0 mOhm

34984

The 34984 is a dual self-protected 4.0 mOhm switch used to replace

electromechanical relays, fuses, and discrete devices in power management

applications. The 34984 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 34984 is packaged in a power-enhanced 12 x 12 mm nonleaded PQFN

package with exposed tabs and powered by SMARTMOS technology.
