Overview
The MIC2544-1BMM-TR is a single-channel high-side power distribution switch manufactured by Microchip Technology. It operates within a supply voltage range of 2.7V to 5.5V and supports an output current up to 1.5A. The device features a programmable current limit adjustable from 100mA to 1.5A, with a maximum on-resistance of 120mΩ. It includes fault protection mechanisms such as thermal shutdown and adjustable current limiting. The component is housed in an 8-MSOP package and functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Integrates programmable current limiting for precise load protection
- Provides thermal shutdown and status flag indication for system monitoring
- Features low on-resistance for efficient power distribution
Applications
- USB hub power switching
- Peripheral power distribution
- ACPI-compliant power management systems
Procurement Notes
Verify the specific suffix 'BMM' against official Microchip documentation to confirm pinout compatibility and electrical characteristics relative to other variants in the MIC2544 series. Ensure the ordering information matches the required package type and tape-and-reel specifications for your manufacturing process.
Selection Notes
Select this component when a single high-side switch with adjustable current limiting is required for 3.3V or 5V systems. Consider the 8-MSOP package size for space-constrained designs. Evaluate the need for programmable limits versus fixed-limit alternatives based on specific load requirements.
Part Context
This part belongs to the MIC2544 family of integrated high-side switches optimized for low-loss DC power switching. These devices are designed for applications requiring advanced configuration and power interface standards, offering a compact solution for managing power distribution in portable and industrial electronics.
Replacement Considerations
The MIC2544-1YMM-TR is a documented substitute within the same family. Verify that the electrical parameters and package dimensions are compatible with the existing design before substitution.
