MIC2548-2YM-TR

Overview

The MIC2548-2YM-TR is a single-channel high-side power switch IC from Microchip Technology, designed for USB power distribution applications. It features a programmable current limit ranging from 100 mA to 1.5 A and a maximum on-resistance of 120 mΩ. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports an output current of up to 500 mA. It includes thermal shutdown with latch functionality and functions within a temperature range of -40°C to +85°C (industrial) or +125°C (extended), housed in an 8-lead SOIC package.

Feature Summary

Programmable current limit allows customization between 100 mA and 1.5 A via external components
Integrated thermal shutdown with latch protection prevents damage during fault conditions
High-side switching topology enables ground-referenced load control

Applications

USB hub power distribution
Peripheral port protection
Battery-powered equipment load switching

Procurement Notes

Verify the specific suffix against official datasheets to confirm temperature range and packaging details. Ensure the ordering part number matches the required operational specifications, as variations exist within the series. Cross-reference the manufacturer's latest documentation to validate compliance with RoHS standards and confirm the active production status before finalizing procurement orders.

Selection Notes

Select this component when a single-channel high-side switch with adjustable current limiting is required. Consider the 120 mΩ on-resistance for efficiency calculations and verify that the 2.7 V to 5.5 V operating range aligns with the system's power supply. Evaluate the need for thermal latch behavior versus non-latch options based on system recovery requirements.

Part Context

This part belongs to the MIC2548 series of power distribution ICs. It serves as a protective element in power routing networks, offering precise current management. The series is engineered for robust performance in consumer electronics and industrial interfaces requiring reliable load switching and overcurrent protection capabilities.
