MIC2526-1BM

Overview

The MIC2526-1BM is a dual integrated high-side power switch designed for Universal Serial Bus (USB) applications. It features two independent switches with individual enable and fault flag functions. The device supports input voltages from 3V to 5.5V, providing a minimum continuous load current of 500mA per port with a maximum on-resistance of 140mΩ. It includes thermal shutdown protection, a 1ms soft-start, and undervoltage lockout. Packaged in an 8-pin SOIC, it requires minimal external components.

Feature Summary

Dual independent high-side power switches optimized for USB compliance
Integrated thermal shutdown and active-high/low enable control
Individual open-drain fault flag pins for status monitoring

Applications

USB host and self-powered hubs
USB bus-powered hubs
Hot plug-in power supplies

Procurement Notes

Verify the specific suffix '1BM' against official Microchip documentation to confirm pin compatibility and enable logic levels. Confirm component status as the base MIC2526 family is marked Not Recommended for New Designs. Ensure sourcing channels provide valid datasheets matching the exact package and temperature grade specifications.

Selection Notes

Select this component for designs requiring dual-channel USB power management with independent control. Verify that the 140mΩ on-resistance meets voltage drop requirements at 500mA loads. Check if the 8-pin SOIC package fits the PCB layout constraints. Consider the Not Recommended for New Design status when planning long-term production lifecycles.

Part Context

The MIC2526 belongs to Micrel's USB power control switch family, which integrates protection features directly into the silicon. This series simplifies circuit design by reducing the need for discrete MOSFETs and protection diodes. The device is part of the broader portfolio managed by Microchip Technology following the acquisition of Micrel.
