Overview
The MIC2546-1YTS is a dual high-side power switch IC from Microchip Technology, designed for low-loss DC power switching and ACPI-compliant power management. It features two independent outputs with a maximum continuous output current of 1.5 A per channel. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports programmable current limiting. It is housed in a 16-pin TSSOP package and functions as an N-channel switch optimized for USB power distribution applications.
Feature Summary
- Dual high-side switch architecture with independent control channels
- Programmable current limit protection for overcurrent scenarios
- ACPI-compliant interface for advanced power management integration
Applications
- USB power distribution hubs
- ACPI-compliant system power management
- Low-loss DC power switching circuits
Procurement Notes
Verify the specific suffix 'TR' indicates tape-and-reel packaging if bulk ordering is required, as the base part number may imply tube packaging. Confirm the 16-pin TSSOP footprint matches your PCB layout constraints. Ensure the 2.7V to 5.5V operating voltage aligns with your system's rail specifications before finalizing procurement.
Selection Notes
Select this component when dual-channel high-side switching with ACPI compliance is required. It is suitable for applications needing 1.5A per channel with programmable current limiting. Consider the 16-pin TSSOP package size relative to available board space. Verify thermal requirements for continuous 1.5A operation in your specific enclosure environment.
Part Context
This part belongs to the MIC254x series of integrated high-side power switches. It is specifically optimized for low-loss DC power switching and power management applications. The series includes variants like the MIC2547, offering similar functionality with potential differences in pinout or feature sets. It serves as a solution for modern portable and desktop power distribution needs.
