Overview
The MIC2549A-2YM-TR is a high-side power switch IC from Microchip Technology, designed for USB power distribution applications. It operates within a supply voltage range of 2.7V to 5.5V and supports a maximum continuous output current of 3A. The device features an on-resistance (RDS(on)) of 35mΩ and utilizes an active-low control input logic. Packaged in an 8-SOIC format, it functions effectively across a temperature range of -40°C to +85°C.
Feature Summary
- Integrated high-side power switching optimized for low-loss DC power management
- Programmable current limit functionality with over-temperature protection
- Active-low control input logic for simplified interface integration
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 'TR' indicates tape-and-reel packaging when sourcing. Confirm that the '2Y' designation corresponds to the correct current limit programming configuration for your design requirements. Ensure compatibility with the 8-SOIC footprint during PCB layout finalization. Cross-reference the manufacturer part number directly with official Microchip documentation to avoid counterfeit components.
Selection Notes
Select this component for applications requiring a single-channel high-side switch with integrated protection features. The 3A current capacity suits moderate load requirements typical in USB peripheral power delivery. Consider the 35mΩ on-resistance for efficiency calculations in battery-powered or low-voltage systems. Verify that the active-low control signal aligns with the host controller's logic levels before implementation.
Part Context
This part belongs to the MIC254xA series of integrated high-side power switches. These devices are engineered for robust performance in power distribution networks. The series offers various current limit options and package configurations to accommodate diverse system constraints while maintaining consistent protection mechanisms.
Replacement Considerations
The MIC2545A-2YM-TR is a documented substitute within the same product family. Both parts share similar high-side switching capabilities and protection features. Verify pinout compatibility and current limit settings before swapping components in existing designs.
