MIC2043-1BM-TR

Overview

The MIC2043-1BM-TR is a high-side power distribution switch manufactured by Microchip Technology. It features a single output channel with an on-resistance of 60 mΩ maximum and supports up to 500 mA continuous load current. The device includes a 3 A current limit, operates within a supply voltage range of 800 mV to 5.5 V, and functions across a temperature range of -40°C to +85°C. Packaged in an 8-pin SOIC, it provides overcurrent protection and low-voltage switching capabilities.

Feature Summary

• High-side power switch topology for efficient load control
• Integrated 3 A current limit for robust overcurrent protection
• Low on-resistance design minimizes conduction losses
• Operates effectively at low supply voltages down to 800 mV

Applications

• Battery-powered portable electronic devices
• Industrial equipment power distribution
• Automotive subsystems and accessories
• Consumer electronics load switching

Procurement Notes

Verify the specific suffix 'BM-TR' against official Microchip documentation to confirm tape-and-reel packaging and exact electrical tolerances. Ensure compatibility with the target PCB footprint and thermal requirements before finalizing procurement orders.

Selection Notes

Select this component when a single-channel high-side switch with integrated current limiting is required. Consider the 60 mΩ on-resistance for efficiency needs and verify that the 3 A limit aligns with the protected load's peak current specifications.

Part Context

This part belongs to the MIC2043 family of power distribution switches. It shares core protection features with other variants but differs in package type and specific manufacturing lot characteristics defined by the BM-TR designation.

Replacement Considerations

MIC2043-1YM-TR: Similar performance with different package or suffix variations.
