MIC2505YM-TR

Overview

The MIC2505YM-TR is a fully integrated high-side power switch manufactured by Microchip Technology. It operates within a supply voltage range of 3V to 7.5V and supports a maximum load current of 2A. The device features an on-resistance of 50mΩ, with a typical turn-on time of 2ms and turn-off time of 20µs. It is housed in an 8-pin SOIC package and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Fully integrated high-side switching capability for single-channel power distribution
• Built-in protection mechanisms including fixed current limiting and thermal shutdown
• Controlled slew rate to minimize inrush current during activation

Applications

• USB port power management and overcurrent protection
• Peripheral device power sequencing in embedded systems
• High-side load switching for low-voltage digital circuits

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package type and tape-and-reel specifications. Ensure the component matches the required operating temperature range and electrical ratings for the target application environment before procurement.

Selection Notes

Select this component when a single-channel high-side switch with 2A capacity is required. Consider the 50mΩ on-resistance for power loss calculations. Verify compatibility with the system's control logic voltage levels and ensure adequate thermal dissipation for the SOIC package under maximum load conditions.
