Overview

Freescale Semiconductor Advance Information Document Number: MC33981 Rev.
6.
0, 5/2007 Single High-Side Switch (4.
0 mΩ), PWM clock up to 60kHz The 33981 is a high-frequency, self-protected 4.
0 mΩ RDS(ON) highside 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.
Features • Single 4.
