MIC2041-1YMM

Overview

The MIC2041-1YMM is a single-channel high-side power distribution switch manufactured by Microchip Technology. It operates within an input voltage range of 0.8V to 5.5V and supports a continuous output current of up to 1.5A. The device features a maximum on-resistance of 75mΩ, adjustable current limiting, and thermal shutdown protection. It includes soft-start circuitry to manage inrush currents and provides a fault status flag for overcurrent or thermal events. The component is housed in an MSOP-8 package and is designed for general-purpose power distribution applications requiring circuit protection.

Feature Summary

• Auto-reset circuit breaker mode that latches the output off upon detecting sustained overcurrent conditions exceeding 28ms
• Integrated soft-start circuitry to minimize inrush current when powering highly capacitive loads
• Output MOSFET reverse current flow block functionality when the device is disabled

Applications

• Multi-port USB power distribution satisfying upstream/downstream power requirements
• General-purpose power distribution circuits requiring integrated short-circuit protection
• Load switching applications with highly capacitive load profiles

Procurement Notes

Verify the specific suffix '1YMM' against official Microchip documentation to confirm pinout and package configuration. Ensure the selected variant matches the required operating temperature range and electrical specifications for the target application environment before finalizing procurement.

Selection Notes

Select this component for applications requiring a single-channel high-side switch with auto-reset capabilities. Consider the 75mΩ on-resistance and 1.5A current limit for low-loss power routing. Verify compatibility with the system's logic levels for the fault status output and ensure adequate thermal management for the intended load conditions.

Part Context

The MIC2041 belongs to the MIC2040/2041 series of single-channel low-voltage power switches. This family is optimized for general-purpose power distribution where circuit protection is critical. The MIC2041 variant specifically distinguishes itself from the MIC2040 by including an auto-reset circuit breaker mode, providing enhanced protection against persistent fault conditions without manual intervention.
