Overview
The MIC2548-1BMM is a single-channel, high-side power distribution switch manufactured by Microchip Technology. It features an N-channel MOSFET output capable of handling up to 1.5A continuous current with a programmable current limit. The device operates within a supply voltage range of 2.7V to 5.5V and includes thermal shutdown protection. Packaged in an 8-pin MSOP footprint, it is designed for low-loss DC power switching applications.
Feature Summary
- Integrates a high-side N-channel power switch with programmable current limiting functionality
- Includes built-in thermal shutdown protection to safeguard against overheating conditions
- Optimized for low on-resistance to minimize power loss during conduction
Applications
- Advanced Configuration and Power Interface (ACPI) power management
- Low-loss DC power distribution systems
- General-purpose load driver circuits requiring overcurrent protection
Procurement Notes
Verify the specific suffix 'BMM' corresponds to the 8-MSOP package and lead-free status when ordering. Confirm that the required current limit settings align with the internal programming options or external resistor requirements if applicable. Ensure the operating voltage range of 2.7V to 5.5V matches the system design constraints before finalizing procurement.
Selection Notes
Select this component for applications requiring a single-channel high-side switch with integrated protection features. Consider the 1.5A current rating and 2.7V–5.5V input range as primary selection criteria. Evaluate the MSOP package size for space-constrained designs. Compare against the MIC2544 series if multiple channels are needed instead of a single channel.
Part Context
The MIC2548-1BMM belongs to the MIC2544/MIC2548 family of integrated high-side power switches. This series is specifically optimized for low-loss DC power switching and power management tasks. The part number indicates a single-channel variant within the broader family, distinguished by its specific packaging and electrical characteristics suitable for portable and industrial electronics.
Replacement Considerations
Direct substitutes may include other single-channel high-side switches from Microchip such as the MIC2544 series variants, provided they match the 8-MSOP package and 1.5A current rating. Verify pin compatibility and voltage ranges before substitution.
