FAN3226CMX-F085

Gate Driver Overview

The FAN3226CMX-F085 is a dual high-speed low-side gate driver manufactured by onsemi, designed to drive N-channel enhancement-mode MOSFETs. It features two independent drivers with inverting configurations, housed in an 8-SOIC package. The device operates within a supply voltage range of 4.5 V to 18 V and delivers a peak output current of 2 A. Key electrical parameters include a rise time of 12 ns and a fall time of 9 ns. It supports an operating temperature range from -40°C to +125°C and includes internal undervoltage lockout functionality.

Gate Driver Feature Summary

• Dual channel architecture providing independent control for low-side switching applications
• High-speed switching capability with matched internal propagation delays between channels
• Integrated undervoltage lockout function to maintain outputs low during insufficient supply conditions

Gate Driver Applications

• Synchronous rectifier circuits requiring critical timing alignment
• Low-side switching for N-channel power MOSFETs
• General purpose power management IC gate driving

Gate Driver Procurement Notes

Verify component authenticity through authorized distribution channels due to end-of-life status. Confirm package integrity and pin configuration compatibility with target PCB footprint. Review latest datasheet revisions for any parameter updates or handling instructions prior to integration into final assembly processes.

Gate Driver Selection Notes

Select this component when dual isolated low-side drive signals are required with moderate current capabilities. The inverting logic simplifies control interface design. Ensure the application voltage remains within the 4.5 V to 18 V operational window. Consider thermal dissipation requirements given the SOIC-8 package constraints for sustained operation.

Gate Driver Part Context

This part belongs to the FAN322x series of dual high-speed low-side gate drivers. It shares functional similarities with variants like the FAN3226TMX-F085 but differs in specific packaging or ordering suffix details. The series is engineered for applications demanding precise timing matching between channels, such as synchronous buck converters.

Gate Driver Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The component status is listed as End-of-Life (EOL). Engineers should consult official manufacturer resources for potential obsolescence management strategies or alternative family members.
