MIC2041-2YMM

Overview

The MIC2041-2YMM is a single-channel high-side power distribution switch manufactured by Microchip Technology. It integrates a MOSFET optimized for general-purpose power distribution applications requiring circuit protection. The device supports an operating voltage range from 0.8V to 5.5V and provides programmable current limiting alongside thermal shutdown capabilities. It features soft start circuitry to minimize inrush current for capacitive loads and includes a fault status output for detecting overcurrent or thermal events. The component is housed in a compact YMM package.

Feature Summary

• Integrates adjustable current limiting and thermal shutdown for load protection
• Features soft start circuitry to manage inrush current on capacitive loads
• Includes a fault status flag output for monitoring overcurrent and thermal conditions
• Supports auto-reset circuit breaker mode that latches off upon prolonged overcurrent

Applications

• General purpose power distribution circuits
• Multi-port USB applications satisfying upstream/downstream power requirements
• Circuit protection for sensitive electronic loads

Procurement Notes

Verify the specific suffix '2YMM' against official Microchip documentation to confirm pinout, package dimensions, and electrical tolerances. Ensure compatibility with system voltage ranges of 0.8V to 5.5V. Confirm RoHS compliance status through the manufacturer's datasheet rather than distributor listings. Cross-reference the part number with the latest revision history to avoid obsolete variants.

Selection Notes

Select this component when designing systems requiring integrated high-side switching with built-in protection mechanisms. It is suitable for applications needing precise control over inrush currents and fault detection via status flags. Consider the 0.8V minimum operating voltage for low-voltage logic interfaces. Evaluate the need for auto-reset functionality versus manual reset based on system reliability requirements.

Part Context

The MIC2041 series belongs to Microchip's portfolio of power supply support circuits designed for robust power management. These devices are engineered to replace discrete protection components, reducing board space and design complexity. The MIC2041 variant specifically adds auto-reset capabilities compared to the latch-off MIC2040, making it distinct within the family for automated recovery scenarios.

Replacement Considerations

The MIC2040-2YMM serves as a functional substitute if auto-reset capability is not required, as it shares similar electrical characteristics but latches off permanently upon fault. Verify package compatibility and pin assignments before substitution.
