Overview
The MIC2546-2BTS-TR is a dual high-side power switch IC from Microchip Technology, designed for low-loss DC power switching. It features two independent channels with adjustable current limits and operates within a supply voltage range of 2.7 V to 5.5 V. Each channel supports an output current of up to 1.5 A with a typical on-resistance of 80 mΩ. The device is housed in a 16-pin TSSOP package and functions across temperatures from -40°C to +85°C.
Feature Summary
- Dual high-side switches with programmable current limiting for precise load protection
- Integrated status flag output for real-time fault detection and system monitoring
- Low on-resistance design optimized for efficient power distribution and minimal heat generation
Applications
- USB power distribution hubs requiring overcurrent protection
- Industrial control systems needing isolated load switching
- Automotive electronics utilizing high-side driver architectures
Procurement Notes
Verify the complete part number including suffixes such as TR for reel packaging. Confirm the specific variant (e.g., B vs Y) matches your current limit requirements. Ensure the TSSOP-16 footprint aligns with your PCB layout. Check RoHS compliance status if required by your manufacturing standards. Validate operating temperature ranges against your environmental specifications.
Selection Notes
Select this component when dual-channel high-side switching with adjustable current limits is required. Compare the 1.5 A rating against peak load demands. Consider the 80 mΩ on-resistance for thermal management calculations. Evaluate the 2.7 V to 5.5 V input range against your system voltage. Assess the need for status flags versus simpler switch configurations.
Part Context
This device belongs to the MIC2546/2547 family of integrated power switches. These components are engineered for applications demanding reliable power distribution with built-in protection mechanisms. The series offers various packages and current ratings to suit different density and performance needs in power management circuits.
Replacement Considerations
Check for direct substitutes like the MIC2546-2YM-TR for similar functionality. Verify pin compatibility and electrical parameters before substitution. Ensure the replacement maintains the same current limit adjustability and package type.
