Overview
The MIC2546-1BTS is a dual high-side power switch optimized for low-loss DC power switching. It features two independent N-channel outputs with a maximum current of 1.5A per channel and a typical on-resistance of 80mΩ. The device operates within a load voltage range of 2.7V to 5.5V. It includes programmable current limiting and a status flag interface. Packaged in a 16-pin TSSOP, it supports surface-mount installation and functions without a separate supply voltage.
Feature Summary
- Dual high-side power switching capability with independent channel control
- Integrated programmable current limit protection for overcurrent conditions
- Status flag output provides real-time fault indication
- Optimized for low-loss DC power distribution applications
Applications
- USB power distribution networks
- Low-loss DC power switching systems
- General power management circuits requiring dual high-side control
Procurement Notes
Verify the specific suffix 'BTS' against the manufacturer's official datasheet DS20006959 to confirm package type and temperature rating. Ensure compatibility with system voltage requirements between 2.7V and 5.5V. Confirm that the 1.5A output current meets design specifications. Check for RoHS compliance details in the final procurement documentation.
Selection Notes
Select this component when dual independent high-side switching is required with integrated current protection. The 80mΩ on-resistance offers efficiency benefits for low-voltage applications. The absence of a required VCC supply simplifies circuit design. Consider the 16-pin TSSOP package constraints for PCB layout and thermal management during selection.
Part Context
The MIC2546 series comprises integrated dual power switches designed for efficient power distribution. This model represents the B-grade variant within the family, typically indicating specific temperature or performance characteristics defined by Microchip Technology. It serves as a solution for managing multiple loads in compact electronic systems.
Replacement Considerations
Direct substitutes include MIC2546-1YTS, MIC2546-2BTS, and MIC2546-2YTS from the same product line. Verify pinout compatibility and electrical parameter alignment before substitution. Cross-reference with MIC2545A-1BM only if functional equivalence is confirmed through detailed datasheet comparison.
