MIC2505-2YM

Overview

The MIC2505-2YM is a fully integrated high-side power switch manufactured by Microchip Technology, designed for USB power distribution applications. It features a single output channel capable of handling up to 2A of continuous current. The device operates within a supply voltage range of 3V to 7.5V and utilizes an 8-pin SOIC package. Key electrical characteristics include a maximum on-resistance of 50mΩ and a typical turn-on time of 2ms. It supports operation across a temperature range of -40°C to +85°C.

Feature Summary

• Fully integrated high-side switch topology for simplified circuit design
• Built-in current limiting and thermal protection mechanisms
• Active-low control input for straightforward logic interfacing
• Open-load detection capability for fault monitoring

Applications

• USB hub power distribution circuits
• Peripheral device power switching
• Battery-powered equipment load management
• Portable electronics power rails

Procurement Notes

Verify the specific suffix '-2' confirms the single-channel 2A variant rather than other configurations in the MIC2505 family. Ensure the 'YM' designation corresponds to the standard 8-pin SOIC package with the specified temperature range. Cross-reference the manufacturer's latest datasheet to confirm pinout compatibility and electrical specifications before finalizing procurement orders.

Selection Notes

Select this component when a single-channel high-side switch with 2A capacity is required for USB or low-voltage DC applications. Consider the 50mΩ on-resistance for efficiency calculations and the 2ms turn-on time for inrush current management. Verify that the open-load detection feature meets system diagnostic requirements compared to variants without this function.

Part Context

This part belongs to the MIC2505 series of USB power switches from Microchip Technology (formerly Micrel). The series includes dual-channel and quad-channel variants such as the MIC2506. The MIC2505-2YM specifically denotes the single-channel version optimized for individual port protection and control in compact surface-mount designs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative single-channel high-side switches from Microchip or other manufacturers based on matching current ratings, package dimensions, and control logic compatibility.
