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

Notes
1. Exceeding voltage limits on INHS, INLS, CONF, CSNS, FS, TEMP, and EN terminals may cause a malfunction or permanent damage to the
device.
2. Continuous high-side output rating as long as maximum junction temperature is not exceeded. Calculation of maximum output current using
package thermal resistance is required.
3. ESD1 testing is performed in accordance with the Human Body Model (CZAP = 100 pF, RZAP = 1500 Ω).
4. ESD2 testing is performed in accordance with the Machine Model (CZAP = 200 pF, RZAP = 0 Ω) and in accordance with the system module
specification with a capacitor > 0.01 µF connected from OUT to GND.
5. Active clamp energy using single-pulse method (L = 16 mH, RL = 0, VPWR = 12 V, TJ = 150°C).
6. Device mounted on a 2s2p test board per JEDEC JESD51-2.
7. Terminal soldering temperature limit is for 10 seconds maximum duration. Not designed for immersion soldering. Exceeding these limits may
cause malfunction or permanent damage to the device.
8. Maximum power dissipation at indicated ambient temperature in free air with no heatsink used.
