Overview
The MIC2546-2BTS is a dual high-side power switch IC from Microchip Technology, housed in a 16-TSSOP package. It features two independent channels with programmable current limits and operates within a supply voltage range of 2.7 V to 5.5 V. Each channel supports a maximum output current of 1.5 A. The device includes fault protection mechanisms such as current limiting and thermal shutdown. It functions across an operating temperature range of -40°C to +85°C.
Feature Summary
- Dual-channel high-side switching architecture
- Programmable current limit functionality
- Integrated thermal and over-current protection
Applications
- USB power distribution systems
- Peripheral load drivers
- Power management circuits
Procurement Notes
Verify the specific suffix 'BTS' against official Microchip documentation to confirm pinout and electrical characteristics. Ensure the component source provides valid traceability for quality assurance. Cross-reference the datasheet revision date to ensure compatibility with design requirements. Confirm that the 16-TSSOP package dimensions match the PCB footprint specifications.
Selection Notes
Select this component when a dual-channel solution with adjustable current limiting is required for high-side applications. Consider the 1.5 A per channel rating and the 2.7 V to 5.5 V input range for system compatibility. Evaluate the TSSOP-16 package constraints for thermal performance and board space. Verify that the programmable current limit settings align with the connected load requirements.
Part Context
This part belongs to the MIC2546/2547 family of integrated high-side power switches. These devices are optimized for low-loss DC power switching and general power management tasks. The family offers dual-channel configurations suitable for distributing power to multiple peripherals or loads efficiently.
Replacement Considerations
Consult official substitution lists for compatible alternatives. Verify that any substitute maintains the same dual-channel configuration, current rating, and package type.
