MIC2044-2YTS-TR

Overview

The MIC2044-2YTS-TR is a high-side power distribution switch manufactured by Microchip Technology. It features an N-channel output with a maximum current limit ranging from 1A to 6A, depending on the specific variant within the series. The device operates within an input voltage range of 0.8V to 5.5V and is housed in a 16-TSSOP package with a width of 4.40mm. It supports tape and reel packaging for automated assembly. The component functions as a low-voltage switch with an on-resistance of approximately 22mΩ to 23mΩ. It is designed for applications requiring precise power management and protection in low-voltage systems.

Feature Summary

• High-side switching capability for efficient power distribution control
• Integrated current limiting function to protect downstream loads
• Low on-resistance design for minimized power loss during operation
• Compatible with standard surface-mount assembly processes

Applications

• USB hub power switching and distribution
• Peripheral port power management in consumer electronics
• Battery-powered device load switching
• General-purpose low-voltage power distribution networks

Procurement Notes

Verify the exact current limit specification (1A vs 6A) against the official datasheet, as the part number suffix may not explicitly denote the current rating in all distributor listings. Confirm the package type is 16-TSSOP and the packaging is Tape & Reel. Ensure the operating temperature range meets the application requirements of -40°C to +85°C. Cross-reference the manufacturer part number with the specific revision or variant documentation to avoid functional mismatches.

Selection Notes

Select this component when a single-channel high-side switch with integrated current limiting is required for low-voltage applications. Consider the input voltage range of 0.8V to 5.5V to ensure compatibility with the system power rail. Evaluate the thermal performance based on the expected load current and the package's thermal characteristics. Compare the on-resistance values across different variants within the MIC2044 family to optimize efficiency for the specific use case.
