MIC2041-1YMM-TR

Overview

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

Feature Summary

• Integrated auto-reset circuit breaker mode that latches the output off during sustained overcurrent conditions exceeding 28ms.
• Built-in soft start circuitry minimizes inrush current when powering highly capacitive loads.
• Provides a dedicated fault status output pin to detect and signal overcurrent and thermal shutdown events.

Applications

• Multi-port USB power distribution systems
• General purpose power distribution requiring circuit protection
• Upstream/downstream power supply management

Procurement Notes

Verify the specific suffix 'YMM' corresponds to the MSOP-8 package and 'TR' indicates tape-and-reel packaging as per the manufacturer's official datasheet. Confirm RoHS compliance status and ensure the operating temperature range aligns with system requirements before finalizing procurement orders.

Selection Notes

Select this component for applications requiring precise control over power delivery with automatic recovery from fault states. The adjustable current limit allows customization for different load profiles, while the compact MSOP-8 package suits space-constrained designs. Ensure the load capacitance does not exceed limits that could compromise soft-start performance.

Part Context

This part belongs to the MIC2040/MIC2041 family of single-channel low-voltage power distribution switches. These devices are optimized for general-purpose power distribution where circuit protection is critical. The family offers programmable current limiting and thermal shutdown to protect both the device and the connected load from damage.

FAQ

How does the MIC2041-1YMM-TR handle overcurrent faults?

It employs an auto-reset circuit breaker mode that latches the output off if an overcurrent condition persists for more than 28ms. The output resets automatically once the load is removed or reduced.

What is the function of the fault status output?

The fault status output provides a signal to detect overcurrent and thermal shutdown fault conditions, allowing the system controller to monitor the health of the power switch.
