Overview
The MIC2544A-1YMM is a high-side power switch IC from Microchip Technology, designed for USB power distribution applications. It features a single output channel with a maximum continuous current of 1.5A and an on-resistance (RdsOn) of 120mΩ. The device operates within a supply voltage range of 2.7V to 5.5V. Key electrical parameters include a maximum run time of 5ms and a maximum idle time of 30μs. It supports programmable current limiting between 100mA and 1.5A. The component is housed in an 8-pin MSOP surface-mount package and functions over an operating temperature range of -40°C to +85°C.
Feature Summary
- Integrates programmable current limit functionality for precise load protection
- Provides high-side switching capability with low on-resistance for efficient power delivery
- Supports ACPI interface standards for system compatibility
Applications
- USB hub power distribution
- Portable device power management
- Peripheral power switching
Procurement Notes
Verify the specific suffix 'YMM' corresponds to the MSOP-8 package variant when sourcing. Confirm that the 'A' designation aligns with the required operational temperature range and electrical characteristics defined in the official datasheet. Ensure ordering documentation matches the exact part number to avoid confusion with non-A variants or different packaging options.
Selection Notes
Select this component for applications requiring a single-channel high-side switch with adjustable current limiting. It is suitable for systems operating between 2.7V and 5.5V where space efficiency is critical due to the compact MSOP package. Consider the 120mΩ on-resistance for thermal management requirements under full 1.5A load conditions.
Part Context
This part belongs to the MIC2544 series of high-side power switches. The series offers solutions for power distribution in portable electronics. The MIC2544A-1YMM specifically denotes the single-output variant with enhanced programmability features compared to basic fixed-limit switches in the family.
Replacement Considerations
Direct substitutes may include other parts from the MIC2544 series with compatible pinouts and electrical ratings. Verify functional equivalence regarding current limit ranges and package dimensions before replacement.
