MIC2042-1BTS-TR

Overview

The MIC2042-1BTS-TR is a high-side power distribution switch manufactured by Microchip Technology. It features a single channel with an active-high enable logic and operates within an input voltage range of 0.8 V to 5.5 V. The device provides adjustable current limiting from 0.5 A to 3 A, ensuring protection against overcurrent conditions. It incorporates thermal shutdown capabilities to safeguard the component during fault events. The IC is housed in a 14-pin TSSOP package and supports operation across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates adjustable current limiting for precise load protection
• Includes thermal shutdown circuitry for enhanced reliability
• Features low on-resistance for efficient power delivery

Applications

• USB port power switching and protection
• Peripheral power distribution in embedded systems
• Load driver applications requiring overcurrent protection

Procurement Notes

Verify the specific suffix 'BTS' corresponds to the 14-pin TSSOP tube or reel configuration as defined by Microchip Technology documentation. Confirm that the current limit setting matches the application requirements, as this variant supports a wide adjustment range. Ensure compatibility with the system's enable logic levels and operating voltage constraints before finalizing procurement orders.

Selection Notes

Select this component when a single-channel high-side switch with adjustable current limiting is required. The 14-pin TSSOP package offers a compact solution for space-constrained designs. Consider the thermal performance and operating temperature range to ensure suitability for the intended environmental conditions. Verify that the input voltage range aligns with the system power supply specifications.

Part Context

This part belongs to the MIC2042 family of USB power switches designed for power distribution applications. The family includes variants with different pin counts and packages, such as SOIC and TSSOP options. The MIC2042 series is characterized by its low on-resistance and robust protection features, making it suitable for managing power to peripheral loads in consumer electronics and industrial equipment.

Replacement Considerations

Direct substitutes include other MIC2042 variants with compatible pinouts and electrical characteristics, such as the MIC2042-1YM or MIC2042-2BTS. Verify package dimensions and pin assignments to ensure mechanical compatibility. Check current limit settings and thermal shutdown thresholds to confirm functional equivalence in the target application.
