MIC2544-1YMM-TR

Power Distribution Switches, Load Drivers Overview

The MIC2544-1YMM-TR is a single-channel high-side power switch IC manufactured by Microchip Technology. It operates within a supply voltage range of 2.7 V to 5.5 V and supports a maximum output current of 1.5 A. The device features an adjustable current limit ranging from 100 mA to 1.5 A, with a typical on-resistance of 80 mΩ and a maximum of 120 mΩ. It includes programmable turn-on time (up to 5 ms) and idle time (up to 22 µs). The component is housed in an 8-MSOP package and functions across a temperature range of -40°C to +85°C.

Power Distribution Switches, Load Drivers Feature Summary

• Integrates adjustable current limiting for precise load protection
• Provides status flag output for fault monitoring
• Features programmable soft-start and idle time control

Power Distribution Switches, Load Drivers Applications

• USB port power distribution and switching
• Peripheral power management in embedded systems
• Hot-swappable load switching applications

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix 'YMM' confirms the 8-MSOP package variant when sourcing. Ensure compatibility with the required thermal dissipation for the target application environment. Confirm RoHS3 compliance status as per the latest manufacturer documentation before finalizing procurement specifications.

Power Distribution Switches, Load Drivers Selection Notes

Select this component for applications requiring a single high-side switch with programmable timing characteristics. The 8-MSOP package suits space-constrained designs. Compare against the MIC2544-1YM-TR if an SOIC package is preferred instead of MSOP. Verify that the 1.5 A current rating meets the peak load requirements of the connected peripheral.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the MIC2544 series of USB power switches. It serves as a single-channel solution within a family that also includes dual-channel variants like the MIC2548. The device replaces legacy discrete switching solutions by integrating protection and control logic into a compact surface-mount package.

Power Distribution Switches, Load Drivers Replacement Considerations

The MIC2544-1YM-TR is a pin-compatible alternative offering the same electrical performance in an 8-SOIC package. Designers should verify footprint differences between MSOP and SOIC packages during substitution.
