Overview
The MIC2549A-2BM is a single-channel, high-side power switch IC from Microchip Technology. It features an N-channel output configured for USB power distribution applications. The device operates within a supply voltage range of 2.7V to 5.5V and supports a maximum load current of 3A. It is housed in an 8-SOIC surface-mount package. Key protection mechanisms include programmable current limiting and over-temperature latch functionality, ensuring robust performance in low-loss DC power switching scenarios.
Feature Summary
- Programmable current limit for precise load management
- Over-temperature latch protection for enhanced reliability
- High-side switching configuration optimized for USB applications
Applications
- USB power distribution systems
- Low-loss DC power switching circuits
- General power management applications requiring high-side control
Procurement Notes
Verify the specific suffix (e.g., -TR for tape-and-reel or tube packaging) against your assembly requirements. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation. Ensure the 8-SOIC footprint matches your PCB layout design before finalizing procurement orders.
Selection Notes
Select this component when a single-channel high-side switch with programmable current limiting is required. It is suitable for applications needing operation between 2.7V and 5.5V. Consider the 8-SOIC package constraints and thermal dissipation capabilities relative to your 3A load requirements and ambient operating conditions.
Part Context
This part belongs to the MIC2549A family of integrated high-side power switches. These devices are specifically engineered for low-loss DC power switching and power management tasks. The family shares common architectural features but varies in channel count and packaging options to suit different integration densities.
Replacement Considerations
Check for direct substitutes within the MIC2545A/MIC2549A series that match the 1-channel configuration and 8-SOIC package. Verify pin compatibility and electrical specifications such as the 2.7V–5.5V operating range and 3A current capacity before substituting.
