Overview
The MIC2544-1BM-TR is a single high-side power switch from Microchip Technology, designed for DC power distribution. It features an N-channel output with a typical on-resistance of 80 mOhms and supports a maximum output current of 1.5 A. The device includes programmable current limiting and operates within a non-inverting input configuration. It is housed in an 8-pin SOIC package and is currently marked as discontinued at Digi-Key.
Feature Summary
- Integrated high-side power switching optimized for low-loss DC applications
- Programmable current limit protection to safeguard downstream loads
- Status flag output for fault monitoring and system diagnostics
Applications
- DC power distribution systems
- Power management circuits requiring load protection
- USB switch ICs with current limiting capabilities
Procurement Notes
Verify component availability status carefully, as this specific part number is listed as discontinued by major distributors such as Digi-Key. Confirm end-of-life documentation and ensure that any remaining stock meets your project's long-term supply requirements before finalizing procurement decisions.
Selection Notes
Select this component only if the 80 mOhm on-resistance and 1.5 A current capacity align with system needs. Consider the non-inverting input logic and SOIC-8 package constraints. Due to its discontinued status, evaluate alternative sources or newer generations within the MIC2544 family for sustainable design integration.
Part Context
This device belongs to the MIC2544 series of programmable current-limit high-side switches. Originally developed by Micrel Semiconductor and later acquired by Microchip Technology, the series is documented under datasheet DS20005725. The product line focuses on integrated solutions for efficient power switching and management in electronic systems.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material. Given the discontinued status, consult Microchip Technology directly for recommended replacements or cross-reference compatible devices within the same high-side switch portfolio.
