MIC94083YFT-TR

Overview

The MIC94083YFT-TR is a high-side load switch from Microchip Technology, designed for power distribution applications. It features a P-channel MOSFET with a maximum on-resistance of 67 mΩ at 5V input. The device supports an operating voltage range of 1.7V to 5.5V and delivers a continuous output current of 2A. It includes an 800 µs soft-start time to limit inrush current. The component operates within a temperature range of -40°C to +125°C and is housed in a compact 4-lead FTDFN package measuring 0.85mm x 0.85mm.

Feature Summary

• High-side load switching capability with low on-resistance
• Integrated soft-start function to manage inrush current
• Wide operating voltage range suitable for various power rails
• Compact surface-mount package design

Applications

• Power distribution in portable electronic devices
• Load switching for USB peripheral protection
• Battery-powered system power management
• General-purpose high-side switching in industrial equipment

Procurement Notes

Verify the specific suffix 'YFT-TR' corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the thermal performance characteristics align with the PCB layout and ambient operating conditions defined in the application environment. Ensure compatibility with the control logic voltage levels used in the target circuit design.

Selection Notes

Select this component when a high-side switch with a 2A current rating and 67 mΩ on-resistance is required. Consider the 1.7V to 5.5V input range for compatibility with single-cell lithium or standard 5V systems. Evaluate the 800 µs soft-start duration against system inrush current constraints. Verify the FTDFN package dimensions fit within the available board space constraints.

Part Context

This part belongs to the MIC9408x family of high-side load switches, which share similar electrical characteristics but vary in current ratings and pin configurations. The MIC94083 specifically offers a 2A capacity, distinguishing it from lower-current variants like the MIC94080 or higher-current options within the same series. All family members utilize the same compact footprint and control interface standards.

Replacement Considerations

Direct substitutes include other parts from the MIC9408x family such as the MIC94080, MIC94081, MIC94082, MIC94084, and MIC94085, provided their specific current ratings meet the application requirements. Cross-referencing datasheets is necessary to confirm identical pinouts and electrical parameters before substitution.
