MIC2043-1BTS-TR

Overview

The MIC2043-1BTS-TR is a high-side power switch IC from Microchip Technology, designed for load distribution in low-voltage systems. It features a single channel with an output current capacity of 500 mA and a current limit of 3 A. The device operates within a supply voltage range of 800 mV to 5.5 V and exhibits a maximum on-resistance of 60 mohms. It supports surface mount installation in a 14-TSSOP package, functioning reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• High-side switching topology for efficient load distribution
• Integrated current limiting protection up to 3 A
• Low on-resistance for minimized power loss
• Compact surface-mount packaging for space-constrained designs

Applications

• Peripheral power switching in embedded systems
• Load distribution in industrial control units
• Power management in automotive electronics
• Battery-powered device circuit protection

Procurement Notes

Verify the specific suffix 'BTS-TR' against the manufacturer's official datasheet to confirm the exact package type (TSSOP) and tape-and-reel configuration. Ensure that the ordering information matches the required quantity per reel and that the component meets RoHS compliance standards as specified in the latest product documentation before finalizing procurement orders.

Selection Notes

Select this component when a single-channel high-side switch with moderate current handling is required. The 500 mA continuous output and 3 A limit suit applications needing basic overcurrent protection. Consider the 14-TSSOP package for PCB layout constraints and verify that the 800 mV minimum supply voltage aligns with the system's logic levels and power rails.

Part Context

This part belongs to the MIC2043 series of power switches, which are engineered for robust load management in various electronic applications. The series offers multiple channel configurations and package options to accommodate diverse design requirements. As a high-side switch, it simplifies control logic by allowing direct interfacing with standard microcontroller outputs without complex level-shifting circuits.

Replacement Considerations

Compatible substitutes include other single-channel high-side switches from Microchip such as the MIC2043-1YM or MIC2043-1BM, provided they match the required current ratings and package dimensions. Verify pinout compatibility and electrical specifications against the original datasheet to ensure seamless integration without redesigning the surrounding circuitry.
