MIC2004-1.2YM5-TR

Overview

The MIC2004-1.2YM5-TR is a high-side power switch IC from Microchip Technology, designed for load distribution applications. It features a P-channel MOSFET in an SOT-23-5 package. The device operates within a supply voltage range of 2.5V to 5.5V and supports a continuous current of 1.2A. Key electrical parameters include a maximum on-resistance of 70 milliohms and a fixed current limit. Integrated protection mechanisms include overcurrent limiting and thermal shutdown. The component functions with a non-inverted control input and offers load release capabilities, operating reliably across a temperature range of -40°C to 85°C.

Feature Summary

• Integrates a high-side P-channel MOSFET for efficient power switching
• Provides built-in protection against overcurrent conditions and excessive temperatures
• Features a non-inverting logic interface for straightforward control integration

Applications

• Load distribution in portable electronic devices
• Power management circuits for consumer electronics
• Hot-swap applications requiring controlled power sequencing

Procurement Notes

Verify the specific suffix YM5 confirms the SOT-23-5 surface-mount package configuration. Ensure the 1.2A current rating aligns with system load requirements. Confirm that the 2.5V to 5.5V operating voltage range matches the target supply rails. Validate that the non-inverted control logic is compatible with the driving microcontroller or processor outputs before finalizing procurement specifications.

Selection Notes

Select this component when a compact high-side switch with integrated protection is required. The 70 milliohm on-resistance minimizes power loss compared to higher resistance alternatives. The fixed current limit simplifies design by removing external sensing components. Consider the SOT-23-5 footprint for space-constrained layouts. Verify that the thermal performance meets the application's dissipation needs under maximum load conditions.

Part Context

This part belongs to the MIC2004 series of single-channel power switches. It complements other variants like the MIC2004-0.5 and MIC2004-0.8 by offering a higher 1.2A current capacity. The series provides a standardized interface for protecting loads in low-voltage systems. It serves as a robust alternative to discrete MOSFET solutions by integrating control and protection logic.

Replacement Considerations

MIC2004-0.8YM5-TR offers a lower 0.8A current limit. MIC2004-0.5YM5-TR provides a reduced 0.5A capacity. Both share identical packaging and control characteristics but differ in maximum current handling.
