MIC2005-0.5YML

Overview

The MIC2005-0.5YML is a fixed current limiting power distribution switch manufactured by Micrel Inc., now part of Microchip Technology. It features a single P-channel MOSFET housed in a compact 6-MLF (2x2 mm) package. The device provides a fixed current limit of 0.5A and supports an input voltage range up to 36V. Key electrical characteristics include a low on-resistance and integrated fault flag output for status monitoring.

Feature Summary

• Fixed current limiting protection prevents overload damage
• Integrated high-side P-channel switch design
• Fault flag output indicates overcurrent events

Applications

• Point-of-load power distribution
• Peripheral circuit protection
• Battery-powered system load switching

Procurement Notes

Verify the manufacturer revision history, as Micrel was acquired by Microsemi and subsequently Microchip. Ensure the ordering suffix matches the required tape-and-reel or cut-tape configuration. Confirm RoHS compliance status and lead-free packaging specifications against the latest datasheet before finalizing procurement orders.

Selection Notes

Select this component when a simple, cost-effective solution for fixed current limiting is required. The 0.5A rating suits low-power peripheral loads. Consider the 6-MLF package size for space-constrained PCB layouts. Verify that the fixed current threshold aligns with the specific load requirements without needing external programming components.

Part Context

This part belongs to the MIC2005 family of power distribution switches designed for protecting downstream circuits from overcurrent conditions. The series offers various current ratings and package options to accommodate different power management needs in portable and industrial electronics.

Replacement Considerations

Check for direct pin-compatible alternatives within the same product family or from other manufacturers offering similar P-channel power switches with comparable current limits and package dimensions.
