MIC2547-2BTS-TR

Overview

The MIC2547-2BTS-TR is a dual high-side power switch from Microchip Technology, optimized for low-loss DC power switching applications. It features an N-channel output configuration with a maximum continuous output current of 1.5 A per channel. The device operates within a supply voltage range of 2.7 V to 5.5 V and is housed in a 16-TSSOP package (0.173", 4.40mm width). It supports an operating temperature range from -40°C to +85°C. Key electrical characteristics include a typical on-resistance of 80 mΩ and non-inverted input logic.

Feature Summary

• Integrated programmable current limit protection with adjustable thresholds
• Built-in thermal shutdown and reverse current blocking capabilities
• Status flag output for monitoring fault conditions
• High-side switching architecture suitable for load driver applications

Applications

• USB hub power distribution
• Peripheral device power management
• Hot-swap controller circuits
• Load switching in embedded systems

Procurement Notes

Verify the specific suffix 'BTS' against the manufacturer's official datasheet to confirm pinout compatibility and package dimensions. Ensure the order quantity aligns with tape-and-reel specifications if automated assembly is required. Cross-reference the RoHS status and environmental compliance data with the latest product release notes before finalizing procurement.

Selection Notes

Select this component when dual independent high-side switching with programmable current limiting is required. The 1.5 A rating suits moderate-load peripherals. Consider the 16-TSSOP package for space-constrained PCB layouts. Verify that the control logic voltage levels are compatible with the system microcontroller or host interface.

Part Context

This part belongs to the MIC2547 series of dual power switches. It shares functional similarities with the MIC2546 but offers distinct packaging or feature variations. The series is designed for robust power distribution in consumer electronics and industrial equipment, providing integrated protection against overcurrent and overheating events.

Replacement Considerations

The MIC2547-1YM is listed as a direct substitute by some distributors. Verify pin-to-pin compatibility and parameter equivalence through official cross-reference tools before replacement.
