MIC2004-0.5YM5

Overview

The MIC2004-0.5YM5 is a single-channel high-side power switch manufactured by Microchip Technology, housed in an SOT-23-5 surface-mount package. It utilizes a P-channel topology and operates within a supply voltage range of 2.5V to 5.5V. The device supports a continuous load current of 500mA with a typical on-resistance of 70 milliohms. Protection features include fixed current limiting and overtemperature shutdown. The component functions as a non-inverting switch with load release capabilities and operates across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a P-channel MOSFET for high-side power switching applications
• Provides integrated protection against overcurrent and thermal overload conditions
• Features a compact SOT-23-5 footprint suitable for space-constrained designs

Applications

• Peripheral power management in portable electronic devices
• Hot-plug insertion protection for bus interfaces
• Power sequencing control in embedded systems

Procurement Notes

Verify the specific suffix designation to confirm the exact current rating variant, as the base model number may correspond to different current options such as 0.5A or 0.8A. Ensure the ordering part number matches the required load current specification for the target application. Confirm that the SOT-23-5 package type aligns with the PCB layout requirements. Check for RoHS compliance status if environmental regulations apply to the end product.

Selection Notes

Select this component when a low-profile, single-channel high-side switch is required for voltages up to 5.5V. Consider the 70 milliohm on-resistance for efficiency calculations at the intended load current. Evaluate the fixed current limit threshold against the maximum expected surge currents of the connected load. Ensure the non-inverting logic interface matches the control signal polarity available in the system design.

Part Context

This part belongs to the MIC2004 family of single-channel power switches designed for protecting loads from electrical faults. The family offers various current ratings and package options to suit different power and size constraints. These devices are commonly used in consumer electronics and industrial equipment where reliable power distribution and fault protection are critical.

Replacement Considerations

Cross-reference with other Microchip MIC200x series variants for different current ratings. Verify pinout compatibility before substituting with similar high-side switches from other manufacturers.
