SEMICONDUCTOR TECHNICAL DATA
Document order number: MC33981
Rev 2.0, 10/2004
Preliminary Information
High-Frequency, High-Current,
Self-Protected High-Side Switch
(4.0 m鈩?up to 60 kHz)
The 33981 is a high-frequency, self-protected 4.0 m鈩?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 12 x 12 nonleaded power-enhanced Power
QFN package with exposed tabs.
