Overview
The MIC2545A-1YTS-TR is a single high-side power switch IC designed for USB power distribution applications. It operates within a supply voltage range of 2.7 V to 5.5 V and features an on-state resistance of 35 mΩ. The device supports programmable current limiting with adjustable thresholds ranging from 0.5 A to 3 A. It is housed in a 14-pin TSSOP package and is supplied in a tape and reel configuration. The component functions with a high active logical level control signal.
Feature Summary
- Single channel high-side power switching capability
- Programmable current limit protection
- Low on-state resistance for efficient power delivery
Applications
- USB power distribution systems
- Peripheral power switching
- Overcurrent protection circuits
Procurement Notes
Verify the specific suffix '1YTS' against official Microchip documentation to confirm pinout, package type, and current limit settings. Ensure the ordering part number matches the required current threshold variant. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement specifications.
Selection Notes
Select this component when a single-channel high-side switch with adjustable current limiting is required for low-voltage applications. Consider the 35 mΩ on-resistance for thermal management and efficiency requirements. Verify that the operating voltage range of 2.7 V to 5.5 V aligns with the system power rail specifications.
Part Context
This part belongs to the MIC2545A family of USB power switches manufactured by Microchip Technology. It is distinct from other variants such as the MIC2545A-2YTS or MIC2045 series, which may offer different channel counts, resistance values, or voltage ranges. The TSSOP-14 package distinguishes it from smaller SOIC packages found in related product lines.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Cross-reference with Microchip's official replacement guide or contact technical support for verified alternatives.
