MIC94072YMT

Overview

The MIC94072YMT is a single-channel high-side power switch manufactured by Microchip Technology, formerly Micrel. It utilizes a P-channel MOSFET architecture to manage load connections within electronic circuits. The device supports an input voltage range of 1.7V to 5.5V and delivers a maximum output current of 1.2A. It features a typical on-resistance of 100mΩ in the 4-TMLF package. Designed for surface-mount installation, it operates reliably across a temperature range of -40°C to +125°C TJ.

Feature Summary

• Integrates a P-channel MOSFET for efficient high-side load switching without requiring external supply voltage.
• Incorporates controlled slew rate functionality to minimize inrush currents and reduce electromagnetic interference during activation.

Applications

• Power distribution management in portable consumer electronics
• Load switching for peripheral devices in industrial control systems
• Battery protection circuits in mobile communication equipment

Procurement Notes

Verify that the component order explicitly specifies the 4-TMLF package variant to ensure physical compatibility with the intended PCB footprint. Confirm that the supplier provides documentation confirming the part originates from Microchip Technology or authorized channels, as the brand history involves acquisition from Micrel. Ensure the ordering suffix matches the required tape and reel configuration for automated assembly processes.

Selection Notes

Select this component when a compact, single-channel solution is required for loads operating between 1.7V and 5.5V. The 100mΩ on-resistance offers a balance between efficiency and cost for currents up to 1.2A. Consider the controlled slew rate feature if system stability against voltage dips is critical. Evaluate the 4-TMLF package dimensions against available board space constraints compared to alternative packages like SC-70-6.

Part Context

The MIC94072 belongs to the MIC9407x series of power switches designed for low-voltage applications. This series emphasizes small form factors and ease of integration into space-constrained designs. The transition from Micrel to Microchip Technology maintains the technical specifications while updating manufacturing and support structures. It serves as a direct replacement for older discrete MOSFET solutions in high-side switching roles.

Replacement Considerations

The MIC94072YC6-TR is a verified substitute offering identical electrical performance in a 6-TSSOP package. Verify that the pinout differences between the 4-TMLF and 6-TSSOP configurations are accommodated by the design layout before substitution.
