MIC2544-2BMM TS

Overview

The MIC2544-2BMM TS is a high-side power switch IC from the MIC2544 series, manufactured by Micrel (Microchip). It features a single output with a maximum on-resistance of 120 mΩ and supports an operating voltage range of 2.7V to 5.5V. The device provides programmable current limiting between 100 mA and 1.5 A, along with soft-start functionality to minimize inrush current. It operates within a temperature range of -40°C to +85°C and is housed in an 8-pin MSOP package.

Feature Summary

Programmable current limit for precise load management
Soft-start circuit minimizes inrush current during enable
Open-drain fault flag indicates current-limiting or thermal shutdown
Compatible with ACPI and USB power distribution requirements

Applications

Advanced Configuration and Power Interface (ACPI) systems
USB power distribution networks
DC power switching applications requiring low-loss management
Peripheral power control in embedded systems

Procurement Notes

Verify the specific suffix 'TS' against official Microchip documentation to confirm tape-and-reel packaging status, as standard datasheets may list 'MM' for tube packaging. Ensure the manufacturer source is identified as Micrel or its successor Microchip Technology to guarantee component authenticity and correct revision level.

Selection Notes

Select this component when a single-channel high-side switch with adjustable current limiting is required. It is suitable for applications needing protection against overcurrent and thermal faults. Compare with the MIC2544A series if lower on-resistance or different package options are needed. Verify logic compatibility for the enable pin before integration.

Part Context

The MIC2544 series integrates high-side switching capabilities with advanced protection features. Manufactured originally by Micrel and now under Microchip Technology, these devices are designed for cost-effective power management. The MIC2544-2 variant specifically denotes the 120 mΩ on-resistance version within the family.
