Overview
The MIC2546-1YTS-TR is a dual high-side power switch IC from Microchip Technology, designed for USB power distribution and ACPI applications. It features two independent channels with programmable current limits ranging from 100 mA to 1.5 A. 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-pin TSSOP package and functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Dual high-side switches with individually programmable current limit settings
- Integrated overcurrent and short-circuit protection mechanisms
- Optimized for low-loss DC power switching in portable systems
Applications
- USB power distribution hubs
- Advanced Configuration and Power Interface (ACPI) compliance circuits
- Portable electronic device power management
Procurement Notes
Verify the specific suffix 'TR' indicates tape and reel packaging when sourcing. Confirm that the '1YTS' designation aligns with the required thermal and electrical specifications for your design. Ensure compatibility with the 16-pin TSSOP footprint during PCB layout validation.
Selection Notes
Select this component for designs requiring dual-channel high-side switching with adjustable current thresholds. It is suitable for applications needing robust protection against shorts and overloads while maintaining low on-resistance. Consider the 16-pin TSSOP form factor for space-constrained layouts.
Part Context
This part belongs to the MIC2546 family of integrated high-side switches. These devices are engineered for efficient power distribution in modern computing and consumer electronics. The series provides reliable performance for managing multiple loads with precise current control capabilities.
Replacement Considerations
Consult official Microchip documentation for direct cross-reference alternatives. Verify pinout compatibility and electrical parameters before substituting with other dual high-side switch models.
