Overview
The MIC2546-2BM is a dual high-side power switch optimized for low-loss DC power switching. It operates with a load voltage range of 2.7V to 5.5V and supports a maximum output current of 1.5A. The device features a typical on-resistance (Rds On) of 80mOhm, ensuring efficient power delivery. Packaged in a 16-SOIC format with a width of 3.90mm, it functions as a programmable current limit switch without requiring a separate supply voltage.
Feature Summary
- Integrated high-side dual power switching capability
- Programmable current limit protection mechanism
- Low on-resistance design for reduced power loss
Applications
- USB port power distribution
- DC power switching circuits
- Load driver applications
Procurement Notes
Verify the manufacturer marking matches Microchip Technology or Micrel Semiconductor specifications. Confirm the package type is 16-SOIC and check for RoHS compliance status. Ensure the part number suffix aligns with the specific reel or tube configuration required for your assembly process.
Selection Notes
Select this component when a dual-channel high-side switch is required for 5V logic systems. Consider the 1.5A current rating and 80mOhm resistance for thermal management. Verify compatibility with USB-based power distribution architectures where programmable current limiting is necessary.
Part Context
This part belongs to the MIC2546/2547 series of integrated power switches. It serves as a solution for distributing power in multi-port systems. The device simplifies circuit design by combining switching and protection functions into a single compact package.
Replacement Considerations
Check for MIC2546-2BM-TR as a tape-and-reel variant. Verify cross-reference availability from authorized distributors if original stock is unavailable.
