Overview
The MIC2548A-2YM is a single high-side power switch IC from Microchip Technology, designed for power distribution applications. It features a programmable current limit ranging from 100 mA to 1.5 A, allowing precise load protection. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports an output current of up to 500 mA continuously. Key electrical parameters include a maximum on-resistance of 120 mΩ, a maximum turn-on time of 5 ms, and a maximum off-time of 22 µs. It functions reliably across a temperature range of -40°C to +85°C.
Feature Summary
- Programmable current limiting capability for customizable load protection
- High-side switching architecture with integrated fault management
- Low on-resistance design for efficient power delivery
Applications
- Power distribution in embedded systems
- Load switching for peripheral devices
- Overcurrent protection circuits
Procurement Notes
Verify the specific suffix 'YM' corresponds to the tube packaging variant when ordering. Confirm that the required current limit settings align with the external programming components specified in the official datasheet. Ensure the operating voltage and thermal conditions remain within the documented limits for reliable performance.
Selection Notes
Select this component for applications requiring a single-channel high-side switch with adjustable current thresholds. Consider the 8-SOIC package for surface-mount assembly. Evaluate the 120 mΩ on-resistance against system power loss requirements. Verify compatibility with the 2.7 V to 5.5 V input voltage range.
Part Context
This part belongs to the MIC2548 series of power switch ICs, which are engineered for robust power distribution tasks. The series typically offers multiple channel options and varying current ratings. The MIC2548A-2YM specifically provides a single-channel solution with programmable limits, fitting into Microchip's portfolio of intelligent power switches.
Replacement Considerations
The MIC2548-2YM is a related variant within the same family. Verify pinout compatibility and parameter equivalence before substitution. No other direct public substitutes are confirmed.
