Overview
The MIC2544-2YMM-TR is a single-channel high-side power switch IC manufactured by Microchip Technology. It features an N-channel output capable of handling up to 1.5A continuous current with a maximum on-resistance of 120 mΩ. The device operates within a supply voltage range of 2.7V to 5.5V and includes programmable current limiting adjustable from 100mA to 1.5A. Integrated protection mechanisms include thermal shutdown and status flagging. The component is housed in an 8-pin MSOP package and supports non-inverting control interfaces.
Feature Summary
- Integrates programmable current limit functionality for precise load management
- Provides comprehensive fault protection including thermal shutdown capabilities
- Features integrated status flagging for real-time operational monitoring
Applications
- USB peripheral power distribution and switching
- Hot-swap applications requiring controlled power sequencing
- Battery-powered systems needing efficient high-side load control
Procurement Notes
Verify the specific suffix 'YMM' corresponds to the 8-MSOP package configuration required for your PCB layout. Confirm that the tape and reel packaging aligns with your automated assembly equipment specifications. Ensure the operating temperature range meets your environmental requirements before finalizing procurement orders.
Selection Notes
Select this component when a single-channel high-side switch with adjustable current limiting is required. It is suitable for applications demanding low on-resistance and integrated thermal protection. Consider the 8-MSOP package size constraints and verify compatibility with the system's logic voltage levels for the enable input.
Part Context
This part belongs to the MIC2544 family of programmable current-limit high-side switches. It serves as a robust solution for managing power delivery to sensitive loads. The series is designed to offer flexibility through adjustable current limits while maintaining compact footprints suitable for space-constrained electronic designs.
Replacement Considerations
Check the MIC2544-1YMM-TR if only a single channel is needed, or the MIC2544-2YM-TR for alternative packaging options within the same functional family.
