Overview
The MP62181DD-LF-P is a single-channel power distribution switch from Monolithic Power Systems. It operates within a supply voltage range of 2.7 V to 5.5 V and supports an output current of 2 A with a fixed current limit of 2.8 A. The device features a maximum on-resistance of 120 mOhms, a maximum turn-on time of 10 ms, and a maximum dwell time of 3 ms. It functions as an active-high switch and is rated for operation between -40°C and +85°C.
Feature Summary
- Integrates fixed current limiting protection at 2.8 A to safeguard downstream loads
- Features low on-resistance for efficient power delivery in compact designs
- Includes configurable timing controls for turn-on and dwell durations
Applications
- Power distribution networks requiring single-channel load switching
- Current-limited power rails for peripheral devices
- Embedded systems utilizing 3.3V or 5V logic levels
Procurement Notes
Verify component status before integration, as the MP62181DD-LF-P is designated as Not Recommended for New Designs (NRND). Confirm availability through authorized distributors and ensure compliance with RoHS standards. Review the official datasheet for pinout compatibility and thermal requirements prior to finalizing procurement plans.
Selection Notes
Select this component for applications requiring a single high-side switch with integrated current limiting. Compare against the MP62180DS-LF-Z if an active-low control interface is preferred instead of active-high. Ensure the required 2A continuous output and 2.8A limit align with system load profiles and thermal constraints.
Part Context
This part belongs to the MPS power switch IC family designed for power distribution. It provides overcurrent protection and load switching capabilities in a small package. The series includes variants with different control polarities and channel counts to suit various embedded power management needs.
Replacement Considerations
The MP62180DS-LF-Z serves as a functional alternative within the same product family. Note that the MP62180DS-LF-Z utilizes an active-low control signal, whereas the MP62181DD-LF-P uses active-high. Verify interface compatibility when substituting.
