MIC2077-1BM-TR

Overview

The MIC2077-1BM-TR is a quad USB high-side power switch manufactured by Microchip Technology. It features four independent N-channel outputs with a 500mA maximum current rating per channel and a typical on-resistance of 100 milliohms. The device operates within a load voltage range of 2.7V to 5.5V and utilizes a 16-SOIC package. Key electrical parameters include fixed current limiting, UVLO, and thermal shutdown protection.

Feature Summary

Integrated fault protection including fixed current limit, overtemperature shutdown, and under-voltage lockout
Controlled slew rate functionality to minimize inrush current during power-up
Status flag output for monitoring channel operational state

Applications

USB hub power distribution
Peripheral port protection
Battery-powered equipment power management

Procurement Notes

Verify the specific suffix '1BM' against the official Microchip datasheet to confirm pinout and feature configuration. Ensure the ordering part number matches the required tape-and-reel quantity. Cross-reference the manufacturer date code and RoHS compliance status with the latest procurement documentation before finalizing orders.

Selection Notes

Select this component when a quad-channel solution is required for USB applications. The 100 milliohm on-resistance supports 500mA loads efficiently. Verify that the 16-SOIC package dimensions fit the PCB layout constraints. Confirm that the fixed current limit settings align with the downstream circuit requirements without external programming.

Part Context

This part belongs to the MIC2077 family of USB power switches. It provides a compact alternative to discrete MOSFET solutions. The device integrates control logic and protection circuits into a single package. It is designed for space-constrained portable electronics requiring reliable power distribution.

Replacement Considerations

Check the MIC2077-1YM-TR for potential pin-compatible alternatives within the same family. Verify functional equivalence regarding current limits and package dimensions before substitution.
