MIC94080YFT-TR

Overview

The MIC94080YFT-TR is a high-side load switch from Microchip Technology designed for power distribution applications. It operates within an input voltage range of 1.7V to 5.5V and features an internal P-channel MOSFET with a maximum on-resistance (RDS(on)) of 67mΩ. The device supports a continuous output current of 2A and includes controlled slew rate functionality to minimize inrush currents. It is housed in a compact 4-TMLF® package measuring 0.85x0.85mm, suitable for surface-mount assembly. The component functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Integrated P-channel pass element providing low on-resistance for efficient power delivery
• Controlled slew rate capability to manage turn-on transients and reduce inrush current
• Compact 4-TMLF® footprint optimized for space-constrained printed circuit board layouts

Applications

• Portable electronic devices requiring efficient power management
• Battery-powered systems needing low quiescent current operation
• Peripheral power switching in consumer electronics

Procurement Notes

Verify the specific suffix YFT against the manufacturer's latest datasheet to confirm package dimensions and tape-and-reel specifications. Ensure compatibility with the target PCB land pattern for the 4-TMLF® package. Confirm RoHS compliance status if required by project regulations. Cross-reference the part number with official Microchip documentation to validate active status and availability before finalizing procurement plans.

Selection Notes

Select this component when a high-side switch with 2A capacity and 67mΩ on-resistance is required within a 1.7V to 5.5V system. The controlled slew rate feature makes it suitable for applications sensitive to inrush currents. Consider the 4-TMLF® package size for dense board designs. Compare against other MIC9408x variants if different current ratings or resistance values are needed.

Part Context

This part belongs to the MIC9408x family of high-side load switches from Microchip Technology. The family shares similar architectural features but varies in electrical parameters such as on-resistance and current handling capabilities. The MIC94080 specifically denotes the variant with 67mΩ RDS(on) and 2A output current rating, distinguishing it from other members like the MIC94081 or MIC94085 which may have different specifications.

Replacement Considerations

Direct substitutes within the same family include MIC94081YFT-TR and MIC94085YFT-TR, though these differ in on-resistance and current ratings. Verify pinout compatibility and thermal performance when considering alternatives. Consult the official datasheet for detailed parameter comparisons to ensure functional equivalence in the specific application.
