MIC2073-1YM-TR

Overview

The MIC2073-1YM-TR is a dual-channel N-Channel high-side power switch manufactured by Microchip Technology. It operates within a load voltage range of 2.7V to 5.5V and supports a maximum output current of 1.25A per channel. The device features a typical on-resistance of 90 milliohms and utilizes an 8-SOIC surface-mount package. Key electrical parameters include fixed current limiting, overtemperature protection, and under-voltage lockout (UVLO). It functions without a separate supply voltage and includes controlled slew rate and status flag capabilities.

Feature Summary

• Dual-channel high-side power switching with independent control
• Integrated fault protection including fixed current limit and thermal shutdown
• Controlled slew rate to minimize inrush current during turn-on

Applications

• General-purpose load driving for peripheral devices
• Voltage level shifting applications requiring high-side switching
• Power distribution in portable electronic systems

Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm that the 8-SOIC package dimensions align with your PCB footprint requirements. Ensure the operating temperature range of -40°C to 85°C meets your environmental specifications. Cross-reference the datasheet for MIC2025/MIC2075 family documentation to confirm pinout compatibility if substituting similar components.

Selection Notes

Select this component for applications requiring dual independent high-side switches in a compact 8-pin package. It is suitable for low-voltage systems between 2.7V and 5.5V where controlled turn-on speed is necessary to prevent bus collapse. Consider the 1.25A current rating against peak load demands. The absence of a Vcc supply simplifies design compared to switches requiring auxiliary power.

Part Context

This part belongs to the MM8™ series of power management ICs from Microchip Technology. It is functionally related to the MIC2075 single-channel and MIC2076 dual-channel variants, offering integrated protection features common to the family. The device serves as a robust solution for managing power delivery to sensitive loads in consumer and industrial electronics.
