MIC2005A-1YM5-TR

Overview

The MIC2005A-1YM5-TR is a single-channel, high-side power switch manufactured by Microchip Technology. It utilizes a P-channel MOSFET architecture to manage load connections within electronic circuits. The device supports a load voltage range of 2.5V to 5.5V and delivers a maximum output current of 500mA. Key electrical characteristics include a typical on-resistance of 170 milliohms and an open-drain fault flag output. Integrated protection mechanisms provide fixed current limiting and thermal shutdown capabilities. The component operates reliably across a temperature range of -40°C to +85°C and is housed in a compact SOT-23-5 surface-mount package.

Feature Summary

• Integrates a P-channel MOSFET for high-side load switching applications
• Provides integrated fixed current limiting and thermal shutdown protection
• Features an open-drain fault flag output for status monitoring

Applications

• Portable consumer electronics requiring efficient power distribution
• Peripheral circuitry management in embedded systems
• Battery-powered devices needing controlled load connection

Procurement Notes

Verify the specific suffix YM5 corresponds to the SOT-23-5 package configuration required for your design. Confirm that the standard lead time aligns with production schedules, as manufacturing dates may vary. Ensure compatibility with the 2.5V to 5.5V load voltage range before finalizing procurement orders.

Selection Notes

Select this component when a single-channel high-side switch with integrated protection is required. It is suitable for loads drawing up to 500mA within the specified voltage window. Consider the SOT-23-5 footprint constraints and the need for an active-low fault indication signal during schematic capture.

Part Context

This part belongs to the MIC2005 family of power switches, designed for portable applications. It succeeds earlier Micrel designs following the acquisition by Microchip Technology. The device serves as a robust solution for managing power delivery to peripheral components while minimizing board space through its small outline transistor packaging.

Replacement Considerations

The MIC2005A-1YM6-TR is a verified substitute offering identical functionality but packaged in an SOT-23-6 footprint. Verify pinout compatibility and PCB layout adjustments if transitioning between the five-pin and six-pin variants.
