Overview
The MIC2545A-1YM-TR is a single high-side power switch IC from Microchip Technology, designed for programmable current limit applications. It operates within a supply voltage range of 2.7 V to 5.5 V and supports an output current up to 3 A. The device features a maximum on-resistance of 50 mΩ and includes protection against overcurrent and thermal conditions. It is housed in an 8-SOIC package suitable for surface mount installation.
Feature Summary
- Programmable current limiting capability
- Single high-side N-channel configuration
- Integrated thermal and overcurrent protection
Applications
- Peripheral power distribution
- Load switching in embedded systems
- Battery-powered device management
Procurement Notes
Verify the complete part number including the -TR suffix to confirm tape-and-reel packaging. Ensure compatibility with the 8-SOIC footprint during PCB layout. Confirm RoHS compliance status through official Microchip documentation before procurement.
Selection Notes
Select this component when a single channel with adjustable current limits is required. Compare on-resistance values against system power loss constraints. Verify that the 2.7 V to 5.5 V operating range aligns with the target system voltage rails.
Part Context
This part belongs to the MIC2545A series of high-side switches. It serves as a discrete solution for protecting loads from excessive current while allowing precise control over power delivery thresholds in compact electronic designs.
Replacement Considerations
Consult official substitution guides for equivalent single-channel high-side switches. Verify pinout compatibility and electrical parameter alignment before replacing existing components in established designs.
