MIC2099-2YMT-TR

Overview

The MIC2099-2YMT-TR is a dual-channel power distribution switch manufactured by Microchip Technology. It utilizes a P-channel MOSFET architecture to manage high-side load connections within electronic systems. The device supports a load voltage range of 2.5V to 5.5V and delivers a maximum output current of 1.1A per channel. Key electrical characteristics include a typical on-resistance of 170 milliohms and an input type that is non-inverting. The component integrates comprehensive fault protection mechanisms, including adjustable current limiting, overtemperature shutdown, and under-voltage lockout (UVLO). It operates across a junction temperature range of -40°C to 125°C and is housed in a compact 6-TMLF package measuring 1.6x1.6 mm.

Feature Summary

• Dual-channel configuration for independent high-side load control
• Integrated programmable current limit with auto-restart capability
• Controlled slew rate to minimize inrush current during turn-on
• Comprehensive fault protection including thermal and UVLO

Applications

• USB hub power distribution management
• Peripheral device hot-swapping interfaces
• Battery-powered equipment load switching
• Portable consumer electronics power rails

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing. Confirm the manufacturer is Microchip Technology, noting historical Micrel branding in older documentation. Ensure the order quantity matches the reel specifications provided by the distributor. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

Selection Notes

Select this component for applications requiring dual-channel power switching with precise current regulation. The low on-resistance minimizes power dissipation compared to higher resistance alternatives. Consider the 6-TMLF package size for space-constrained PCB layouts. Ensure the system voltage remains within the 2.5V to 5.5V operating window for reliable performance.

Part Context

This part belongs to the MIC2099 family of current-limiting power distribution switches. It serves as a dual-channel variant within the lineup, offering two independent switches in a single package. The family is designed for USB and general-purpose power distribution, providing robust protection against short circuits and overloads in portable and industrial applications.

Replacement Considerations

MIC2097-1YMT-TR is documented as a parameter-equivalent substitute option.
