Advance Information

* This document contains certain information on a new product.

Specifications and information herein are subject to change without notice.

Single High-Side Switch

(4.0 m

Ω), PWM clock up to 60kHz

The 33981 is a high-frequency, self-protected 4.0 m

Ω 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 in-rush current, as well as motors and all types of resistive and

inductive loads.

The 33981 is packaged in a 12 x 12 non-leaded power-enhanced

Power QFN package with exposed tabs.
