MIC2018YML-TR

Overview

The MIC2018YML-TR is a single-channel, high-side power switch featuring a P-channel MOSFET output. It supports load voltages from 2.5V to 5.5V with a maximum continuous output current of 2A. The device exhibits a typical on-resistance of 70 milliohms and utilizes a non-inverting open/switch interface. Integrated protections include adjustable current limiting and overtemperature shutdown. It operates within a temperature range of -40°C to +85°C and is housed in a compact 6-DFN (2x2) package.

Feature Summary

• Integrates adjustable current limiting and overtemperature protection for robust fault management.
• Features controlled slew rate to minimize inrush current and system noise during activation.
• Utilizes a non-inverting input interface for straightforward logic control compatibility.

Applications

• High-side switching for peripheral power rails in embedded systems
• Load distribution in portable consumer electronics
• Power sequencing and hot-swapping applications

Procurement Notes

Verify the specific suffix 'YML-TR' corresponds to the 6-DFN surface-mount package and tape-and-reel delivery format. Confirm that the required operating voltage range aligns with the 2.5V to 5.5V specification. Ensure thermal design accounts for the junction-to-ambient characteristics of the small outline package under maximum load conditions.

Selection Notes

Select this component when a single-channel high-side switch with integrated protection is required for low-voltage loads. Consider the 2A current capacity and 70 milliohm on-resistance for efficiency requirements. Evaluate the need for adjustable current limiting versus fixed limits provided by other family members.

Part Context

This part belongs to the MIC20xx family of power switches manufactured by Microchip Technology. It serves as a compact solution for managing power distribution in space-constrained designs. The device replaces discrete MOSFET solutions by integrating control logic and protection circuits into a single semiconductor die.

Replacement Considerations

MIC2008YML-TR is documented as a parameter-equivalent substitute within the same product family.
