MIC2044-1YTS-TR

Overview

The MIC2044-1YTS-TR is a high-side power distribution switch manufactured by Microchip Technology. It features an N-channel output with a typical on-resistance of 20 mΩ and supports a maximum continuous output current ranging from 1 A to 6 A. The device operates within a load voltage range of 0.8 V to 5.5 V and a supply voltage range of 1.6 V to 5.5 V. It is housed in a 16-pin TSSOP package and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates slew rate control to minimize inrush currents during turn-on events.
• Provides comprehensive fault protection including overcurrent, short-circuit, and thermal shutdown capabilities.
• Includes a status flag output to indicate active fault conditions or normal operation.

Applications

• Power distribution in portable consumer electronics
• Load switching for peripheral devices in industrial systems
• Hot-swap applications requiring controlled current ramp-up

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package type and tape-and-reel specifications. Ensure the component matches the required electrical ratings for your target application environment. Cross-reference the manufacturer part number with authorized distributors to guarantee authenticity and traceability.

Selection Notes

Select this component when low on-resistance and precise current limiting are critical for system efficiency. Consider the 16-TSSOP package constraints for PCB layout and thermal management. Evaluate the input voltage requirements against the 1.6 V minimum supply threshold to ensure reliable logic-level control compatibility.

Part Context

This part belongs to the MIC2044 series of power distribution switches designed for low-voltage applications. It serves as a robust solution for managing power delivery to sensitive loads while protecting the source from fault conditions. The series emphasizes reliability and compact integration for modern electronic designs.

Replacement Considerations

Consult Microchip's official cross-reference tools for verified substitutes. Ensure any replacement maintains compatible pinout, voltage ratings, and fault protection characteristics to avoid redesign efforts.

FAQ

What is the function of the status flag?

The status flag provides a digital signal indicating whether the switch is in a fault state or operating normally.

How does slew rate control benefit the circuit?

It limits the rate of voltage rise at the output, reducing inrush currents that could damage connected loads or cause voltage drops.
