SEMICONDUCTOR TECHNICAL DATA

Preliminary Information

33981

High-Frequency, High-Current,

Self-Protected High-Side Switch

(4.0 mΩ up to 60 kHz)

HIGH-SIDE SWITCH

4.0 mΩ

The 33981 is a high-frequency, self-protected 4.0 mΩ R_DS(ON)high-side

switch used to replace electromechanical relays, fuses, and discrete devices

in power management applications.

The 33981 can be controlled by pulse-width modulation (PWM) with a

frequency up to 60 kHz. It is designed for harsh environments, and it includes

self-recovery features. The 33981 is suitable for loads with high inrush current,

as well as motors and all types of resistive and inductive loads.

The 33981 is packaged in a 12x 12 nonleaded power-enhanced Power

QFN package with exposed tabs.
