Rev 2.0, 10/2004
Preliminary Information
High-Frequency, High-Current,
Self-Protected High-Side Switch
(4.0 mup to 60 kHz)
The 33981 is a high-frequency, self-protected 4.0 mRDS(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 mRDS(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
