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 mΩ up to 60 kHz)

The 33981 is a high-frequency, self-protected 4.0 mΩ RDS(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.

Features

• Single 4.0 mΩ RDS(ON) Maximum High-Side Switch

• PWM Capability up to 60 kHz with Duty Cycle from 5% to 100%

• Very Low Standby Current

• Slew Rate Control with External Capacitor

• Overcurrent and Overtemperature Protection, Undervoltage Shutdown

and Fault Reporting

• Reverse Battery Protection

• Gate Drive Signal for External Low-Side N-Channel MOSFET with

Protection Features

• Output Current Monitoring

• Temperature Feedback
