Overview
The MIC2544A-2YM-TR is a single-channel high-side power switch manufactured by Microchip Technology. It operates within a supply voltage range of 2.7V to 5.5V and supports load currents from 0.1A to 1.5A with a programmable current limit. The device features an N-channel output in an 8-pin SOIC package. Key electrical characteristics include a typical on-resistance of 80 milliohms and a maximum on-resistance of 120 milliohms. It includes adjustable current limiting, overtemperature protection, and status flag outputs.
Feature Summary
- Programmable current limiting allows precise control of load current thresholds.
- Integrated thermal shutdown protects the device against overheating conditions.
- Status flag output provides real-time indication of operational state or fault conditions.
Applications
- USB port power distribution and switching
- Peripheral device power management
- High-side load switching in embedded systems
Procurement Notes
Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm the 'A' variant designation matches the required specifications for your design. Ensure the 8-SOIC package dimensions align with your PCB footprint requirements. Check for RoHS compliance documentation if environmental regulations apply to your manufacturing process.
Selection Notes
Select this component for applications requiring a single high-side switch with adjustable current limits. It is suitable for low-voltage systems operating between 2.7V and 5.5V. Consider the 80 milliohm typical on-resistance for efficiency calculations. The integrated thermal protection simplifies system design by reducing external component count.
Part Context
This part belongs to the MIC2544 family of high-side switches. It is functionally similar to the MIC2544-1YM-TR but may differ in specific electrical parameters or revision levels. The MIC2544 series is designed for power distribution applications requiring compact solutions with built-in protection features.
Replacement Considerations
The MIC2544-1YM-TR is a related single-channel variant within the same family. Verify pinout compatibility and specific current limit ranges before substitution. Cross-reference datasheets to ensure equivalent thermal and electrical performance characteristics match the original design requirements.
