Overview
The MIC2548-2YMM is a single high-side power switch IC from Microchip Technology, designed for programmable current limiting in power distribution applications. It operates within a supply voltage range of 2.7 V to 5.5 V and supports an output current up to 500 mA with a configurable current limit between 100 mA and 1.5 A. The device features a maximum on-resistance of 120 mΩ, ensuring efficient power delivery. Key timing parameters include a maximum turn-on time of 5 ms and a maximum off-time of 22 µs. It is rated for operation across a temperature range of -40°C to +85°C and is available in an 8-pin MSOP surface-mount package.
Feature Summary
- Programmable current limit allows customization of protection thresholds from 100 mA to 1.5 A.
- Single high-side switching architecture simplifies circuit design for load management.
- Low on-resistance minimizes power loss during normal operation.
Applications
- USB port power distribution and protection
- Peripheral power switching in embedded systems
- Battery-powered device load management
Procurement Notes
Verify the specific ordering suffix matches the required package type and tape/reel configuration. Confirm that the component meets RoHS compliance requirements for your assembly process. Ensure the supplier provides valid traceability documentation. Check for any recent lifecycle status updates or obsolescence notices directly from Microchip Technology before finalizing procurement plans.
Selection Notes
Select this component when a single-channel high-side switch with adjustable current limiting is required. Consider the 120 mΩ on-resistance for thermal management calculations. Evaluate the 2.7 V to 5.5 V operating range against your system's supply voltage. The MSOP package is suitable for space-constrained designs requiring surface-mount technology.
Part Context
The MIC2548 series includes variants such as the MIC2548-1YMM and MIC2548-2YM, offering different pin counts and configurations. The MIC2548-2YMM specifically denotes the 8-pin MSOP package version. This part belongs to Microchip's broader portfolio of power distribution ICs designed for reliable load switching in consumer and industrial electronics.
Replacement Considerations
Public confirmed substitute part numbers are not provided in the source data. Consult Microchip Technology for authorized alternatives or cross-reference options based on electrical specifications and package compatibility.
