33981
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 mm non-leaded power-enhanced
PQFN 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
• Over-current and over-temperature protection, under-voltage
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
5. Device mounted on a 2s2p test board per JEDEC JESD51-2.
6. Pin soldering temperature limit is for 40 seconds maximum duration. Not designed for immersion soldering. Exceeding these limits may
cause malfunction or permanent damage to the device.
7. Freescale’s Package Reflow capability meets Pb-free requirements for JEDEC standard J-STD-020. For Peak Package Reflow
Temperature and Moisture Sensitivity Levels (MSL), Go to www.freescale.com, search by part number [e.g. remove prefixes/suffixes
and enter the core ID to view all orderable parts. (i.e. MC33xxxD enter 33xxx), and review parametrics.
