MIC2025-1FBM-TR

Overview

The MIC2025-1FBM-TR is a high-side N-channel power distribution switch manufactured by Microchip Technology. It operates within a load voltage range of 2.7V to 5.5V and supports a maximum output current of 850mA. The device features a typical on-resistance of 140mΩ and utilizes an 8-SOIC package with a width of 3.90mm. Designed for general-purpose applications, it includes integrated fault protection mechanisms such as fixed current limiting, overtemperature shutdown, and under-voltage lockout (UVLO).

Feature Summary

• Integrated circuit protection including fixed current limiting, thermal shutdown, and under-voltage lockout.
• High-side switching topology optimized for general-purpose power distribution.
• Controlled slew rate functionality to minimize inrush current during turn-on.

Applications

• General-purpose power distribution systems requiring circuit protection.
• USB-powered peripheral devices and hubs.
• Portable electronic equipment operating within 2.7V to 5.5V supply ranges.

Procurement Notes

Verify the specific suffix 'FBM' against the official Microchip datasheet to confirm package dimensions and marking details. Ensure compatibility with 8-SOIC footprints during PCB layout. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before finalizing procurement specifications.

Selection Notes

Select this component when a single-channel high-side switch with robust fault protection is required. Compare the 140mΩ on-resistance against system power loss constraints. Verify that the 850mA current rating exceeds the maximum load requirements. Consider the 8-SOIC package size relative to available board space.

Part Context

This part belongs to the MIC2025 family of high-side MOSFET switches from Microchip Technology.
