MIC2546-2YTS-TR

Overview

The MIC2546-2YTS-TR is a dual programmable current limit single high-side power switch IC manufactured by Microchip Technology. It 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. The device features a typical on-resistance (Rds On) of 80 mOhm and is housed in a 16-TSSOP package. It functions as a USB power switch with adjustable current limiting capabilities. The component is rated for operation between -40°C and +85°C ambient temperature.

Feature Summary

• Dual high-side switching configuration with independent control
• Programmable current limit protection for load safety
• Low on-resistance for efficient power distribution
• Non-inverting input logic for straightforward integration

Applications

• USB power distribution systems
• Load driver circuits requiring overcurrent protection
• Power management units in embedded devices

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing. Confirm the manufacturer is Microchip Technology, noting previous association with Micrel. Ensure the 16-TSSOP package variant matches your PCB footprint requirements. Cross-reference the datasheet for exact pinout definitions before finalizing procurement specifications.

Selection Notes

Select this component for applications requiring dual-channel high-side switching with precise current limiting. The 1.5 A output rating suits moderate load requirements. Consider the 80 mOhm Rds On for thermal management efficiency. The wide operating voltage range accommodates standard 3.3 V and 5 V systems. Verify compatibility with non-inverting control signals.

Part Context

This part belongs to the MIC2546 family of power distribution switches. It serves as a solution for protecting downstream loads from overcurrent conditions while providing isolated switching capability. The device integrates protection features typically found in discrete solutions into a compact integrated circuit format.

Replacement Considerations

Check for direct substitutes within the MIC2546 series or compatible dual-channel high-side switches from Microchip. Verify pin-to-pin compatibility if replacing with similar packages like TSSOP-16 variants.
