MIC2546-2YTS

Overview

The MIC2546-2YTS is a dual high-side power switch IC designed for USB power distribution applications. It features two independent channels, each capable of delivering up to 1.5 A of output current. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports adjustable current limiting for precise load protection. It is housed in a 16-TSSOP surface-mount package and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel architecture providing independent high-side switching control for separate loads.

Applications

• USB hub power distribution
• Peripheral port protection
• Battery-powered device power management

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package type and tape-and-reel specifications. Ensure the component matches the required current limit settings and thermal performance for the target application environment before finalizing procurement.

Selection Notes

Select this component when dual isolated high-side switching with programmable current limits is required. Confirm that the 1.5 A per channel rating meets load demands and that the 16-TSSOP footprint fits the PCB layout constraints.

Part Context

This part belongs to Microchip's family of USB power switches, which integrate current limiting and over-temperature protection. It serves as a protective interface between power sources and downstream USB peripherals, ensuring system stability during fault conditions.

Replacement Considerations

Consult official substitution guides for compatible alternatives. Verify pin compatibility and electrical parameters before replacing with other dual high-side switches from the same or different manufacturers.
