MIC2097-1YMT-TR

Overview

The MIC2097-1YMT-TR is a high-side power distribution switch from Microchip Technology, designed for USB and general-purpose load driving applications. It features a P-channel MOSFET output with a maximum continuous current of 1.1A and a typical on-resistance of 170 milliohms. The device operates within a load voltage range of 2.5V to 5.5V and utilizes an On/Off interface. Key electrical characteristics include adjustable current limiting, controlled slew rate, and UVLO protection. It is housed in a compact 6-TMLF (1.6x1.6) surface-mount package with exposed pad.

Feature Summary

• Integrated kickstart circuitry to support low-power USB ports during cold plug events
• Programmable current limit allows adaptation to various load requirements
• Controlled slew rate minimizes inrush current and system noise
• Comprehensive fault protection including thermal shutdown and under-voltage lockout

Applications

• USB hub power switching
• Peripheral port protection
• General-purpose high-side load switching
• Hot-pluggable system bus protection

Procurement Notes

Verify the specific suffix YMT against the official Microchip datasheet to confirm the 6-TMLF package and tape-and-reel configuration. Ensure the ordering part number matches the exact temperature grade and packaging variant required for your assembly process. Cross-reference the manufacturer's latest product change notices to confirm any recent labeling or material updates.

Selection Notes

Select this component when a single-channel high-side switch with programmable current limiting is required for 3.3V or 5V systems. The integrated kickstart feature makes it suitable for powering devices with significant input capacitance. Compare its 1.1A rating and 170mΩ resistance against lower-current alternatives if space or cost constraints exist.

Part Context

This part belongs to the MIC2095/97/98/99 family of USB power switches. It shares architectural similarities with the MIC2099 but differs in specific internal threshold settings and kickstart implementation. The family is designed to replace discrete FET solutions, offering integrated protection in a small footprint suitable for portable electronics.

Replacement Considerations

MIC2099-1YMT-TR is a parameter-equivalent alternative within the same family.
