Overview
The MIC2544A-2YMM is a high-side power switch IC from Microchip Technology, designed for programmable current limit applications. It features an N-channel switch element with a maximum continuous current of 1.5A and a low on-resistance (RdsOn) of 80mΩ at 5V. The device operates within a supply voltage range of 2.7V to 5.5V and includes thermal shutdown protection. Packaged in an 8-pin MSOP (3x3x1.0mm) surface-mount format, it supports ACPI interface standards and functions effectively across temperatures from -40°C to +85°C.
Feature Summary
- Programmable current limiting capability for precise load protection
- Integrated thermal shutdown mechanism to prevent overheating damage
- Low on-resistance design ensuring efficient power distribution
- Compact MSOP package suitable for space-constrained PCB layouts
Applications
- USB power distribution systems
- Peripheral driver circuits requiring overcurrent protection
- High-side switching in portable electronic devices
- Battery-powered equipment load management
Procurement Notes
Verify the specific suffix 'YMM' against official Microchip documentation to confirm the MSOP-8 package variant and lead-free status. Ensure that the procurement channel provides valid traceability for the Microchip brand. Cross-reference the part number with the latest datasheet revision to confirm compatibility with ACPI interface requirements and thermal specifications before finalizing orders.
Selection Notes
Select this component when a high-side switch with programmable current limits is required for loads up to 1.5A. It is suitable for applications needing low on-resistance and integrated thermal protection within a compact footprint. Consider the 2.7V to 5.5V operating range and ensure the system voltage aligns with these parameters. Verify that the MSOP-8 package fits the available board space and thermal dissipation requirements.
Part Context
This part belongs to the MIC2544 series of high-side switches from Microchip Technology. It shares functional similarities with variants like MIC2544A-1YM but differs in package configuration and specific electrical characteristics. The series is designed for power distribution applications, offering robust protection features such as thermal shutdown and current limiting in a small surface-mount package.
Replacement Considerations
Publicly confirmed substitute part numbers are not explicitly listed in the provided source material. Users should consult official Microchip resources or distributor cross-reference tools for verified alternatives.
