Overview
The MIC2546-1YM-TR is a dual programmable current limit single high-side switch manufactured by Microchip Technology. It operates within a supply voltage range of 2.7 V to 5.5 V and supports an output current of 1.5 A. The device features adjustable current limiting, overtemperature protection, and status flags. It is housed in a TSSOP-16 package and functions as a USB power switch with high-side configuration.
Feature Summary
- Dual channel architecture with independent control
- Programmable current limiting for load protection
- Integrated overtemperature shutdown mechanism
- Status flag output for fault indication
Applications
- USB port power distribution
- Peripheral device power switching
- Load protection circuits
Procurement Notes
Verify the specific suffix 'YTS' against standard datasheet listings which typically denote 'YM'. Confirm package type matches TSSOP-16 requirements. Ensure RoHS compliance documentation aligns with project specifications. Cross-reference manufacturer part numbers to avoid confusion between similar Micrel/Microchip legacy codes.
Selection Notes
Select this component when dual high-side switching with programmable current limits is required. Compare against MIC2544 for single-channel needs or MIC2548 for alternative pinouts. Ensure the 1.5 A output capability meets load demands. Verify thermal performance within the -40°C to +85°C operating range for the target application environment.
Part Context
This part belongs to the MIC254x series of USB power switches from Microchip Technology, formerly Micrel. It provides robust protection features for downstream loads. The series includes variants like MIC2544 and MIC2548, offering different channel counts and packaging options for various power distribution applications.
Replacement Considerations
MIC2546-1YM-TR serves as a direct functional equivalent to earlier Micrel-branded versions. Check for package compatibility if substituting with MIC2546-1YM. Verify current limit programming resistor values remain consistent across replacements.
