Overview
The MIC2546-1BTS-TR is a dual high-side power switch IC from Microchip Technology, designed for low-loss DC power switching and USB power distribution applications. It features two independent channels with adjustable current limiting, overtemperature protection, and reverse current blocking. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports an output current of up to 1.5 A per channel. It is housed in a 16-TSSOP package and functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Dual high-side switch configuration with independent channel control
- Integrated adjustable current limiting for precise load management
- Built-in overtemperature and reverse current protection mechanisms
Applications
- USB power distribution hubs
- Low-loss DC power switching systems
- Peripheral power management circuits
Procurement Notes
Verify the specific suffix 'BTS' against the manufacturer's official datasheet to confirm pinout compatibility and thermal characteristics. Ensure the reel packaging specification matches your automated assembly requirements. Cross-reference the RoHS compliance status with the latest product release notes to guarantee adherence to environmental regulations for your target market.
Selection Notes
Select this component when dual-channel high-side switching with integrated fault protection is required. It is suitable for designs needing adjustable current limits rather than fixed thresholds. Consider the 16-TSSOP footprint for PCB layout constraints. Evaluate the 80 mΩ typical on-resistance for efficiency calculations in low-voltage applications.
Part Context
This part belongs to the MIC2546 family of integrated power switches optimized for power management. It serves as a robust solution for protecting downstream loads in portable and industrial electronics. The series offers various package options and channel configurations to suit different density and performance needs.
Replacement Considerations
The MIC2546-1YTS-TR is a documented variant within the same family, offering similar functionality but potentially differing in specific electrical tolerances or package markings. Verify cross-compatibility by comparing detailed parameter tables before substitution.
