MIC2073-2YM-TR

Overview

The MIC2073-2YM-TR is a high-side power switch from Microchip Technology, designed for USB and general-purpose load driving applications. It features a single output channel with a maximum continuous current of 500 mA and a fixed current limit of 900 mA. The device operates within a supply voltage range of 2.7 V to 5.5 V and includes an N-channel MOSFET with a typical on-resistance (RdsOn) of 115 mΩ. It is housed in an 8-pin SOIC package and supports non-inverting input control. The component provides fault protection against overcurrent and thermal conditions, ensuring reliable operation in power distribution circuits.

Feature Summary

• High-side configuration with controlled slew rate to minimize inrush current
• Integrated status flag for monitoring output state
• Fixed current limiting and thermal shutdown protection

Applications

• USB port power switching and protection
• General-purpose load driving in embedded systems
• Power distribution units requiring high-side control

Procurement Notes

Verify the specific suffix -TR indicates tape-and-reel packaging when ordering. Confirm RoHS compliance and lead-free status as per the manufacturer's latest documentation. Ensure the operating temperature range of -40°C to +85°C aligns with your system requirements. Check for any recent product change notices regarding packaging or testing sites.

Selection Notes

Select this component for applications requiring a single high-side switch with moderate current capacity up to 500 mA. The 115 mΩ on-resistance offers a balance between efficiency and cost. Consider the 8-pin SOIC package for surface-mount assembly. Verify that the non-inverting logic interface matches your control signals. This part is suitable for USB peripherals and low-power industrial loads.

Part Context

The MIC2073 belongs to Microchip's family of USB power switches and load drivers. It shares functional similarities with the MIC2075 and MIC2076 but differs in output count and specific electrical characteristics. The -2YM-TR designation specifies the single-channel variant in an SOIC-8 package with reel packaging. It is distinct from the MIC2043, which supports higher currents, and the MIC2077, which offers multiple channels.

Replacement Considerations

The MIC2075-2YMM-TR is a related single-channel high-side switch with similar functionality but may differ in package type (MSOP-8 vs SOIC-8) and exact RdsOn values. Direct pin-to-pin replacement requires verifying package compatibility and electrical parameter alignment. No other direct substitutes are explicitly confirmed in the provided data.
