MIC2075-1YMM-TR

Overview

The MIC2075-1YMM-TR is a high-side power switch IC from Microchip Technology, designed for USB power distribution applications. It features an N-channel output with a maximum continuous current of 500mA and a fixed current limit of 700mA. The device operates within a load voltage range of 2.7V to 5.5V and utilizes an 8-MSOP package. Key electrical characteristics include a typical on-resistance of 90 milliohms and a maximum on-time of 6 milliseconds. It incorporates controlled slew rate functionality and status flag outputs.

Feature Summary

• Integrated high-side power switching with fixed current limiting protection
• Controlled slew rate capability to minimize inrush current during turn-on
• Built-in fault protection including over-temperature, under-voltage lockout, and short-circuit detection
• Status flag output indicating active state or fault conditions

Applications

• USB port power distribution and protection
• High-side load switching in portable electronic devices
• Power management circuits requiring controlled turn-on timing
• Battery-powered systems needing efficient power path management

Procurement Notes

Verify the specific package variant (MSOP-8) and suffix (-TR for tape and reel) against your bill of materials. Confirm that the 500mA continuous current rating aligns with your thermal design constraints. Ensure compatibility with the 2.7V to 5.5V input voltage range. Check RoHS3 compliance requirements if applicable to your manufacturing process. Validate pinout compatibility if replacing existing components.

Selection Notes

Select this component when a single-channel high-side switch with integrated current limiting is required. The 90 milliohm on-resistance offers low conduction losses compared to higher resistance alternatives. The controlled slew rate makes it suitable for sensitive USB loads. Consider the 8-MSOP package size for space-constrained designs. Evaluate the 700mA hard limit against potential surge currents in your application.

Part Context

This part belongs to the MIC2075 series of USB high-side power switches. It shares functional similarities with the MIC2075-1YM-TR but differs in packaging, utilizing MSOP-8 instead of SOIC-8. The series is designed for protecting downstream loads from overcurrent and short circuits while providing status feedback. It complements other variants like the dual-channel MIC2076.

FAQ

What is the difference between MIC2075-1YMM-TR and MIC2075-1YM-TR?

The primary difference is the package type. MIC2075-1YMM-TR uses an 8-MSOP package, while MIC2075-1YM-TR uses an 8-SOIC package. Both share identical electrical specifications and functionality.

How does the controlled slew rate benefit the circuit?

The controlled slew rate limits the rate of voltage rise at the output, reducing inrush current when connecting capacitive loads. This helps prevent triggering the current limit prematurely and reduces stress on the power source.
