FAN3226TMPX

Gate Driver Overview

The FAN3226TMPX is a dual low-side MOSFET gate driver manufactured by onsemi, designed for high-speed switching applications. It operates within a supply voltage range of 4.5 V to 18 V and delivers a peak output current of 2 A per channel. The device features an inverting logic configuration with typical rise and fall times of 12 ns and 9 ns, respectively. It is housed in an 8-MLP (3x3 mm) surface-mount package and supports an operating temperature range from -40°C to +125°C. The quiescent supply current is specified at 750 µA.

Gate Driver Feature Summary

• Dual-channel architecture providing independent control for two low-side MOSFETs
• High-speed switching capability with nanosecond-level propagation delays
• Inverting input configuration compatible with standard CMOS logic levels
• Robust thermal performance supporting operation up to 125°C junction temperature

Gate Driver Applications

• DC-DC converter synchronous rectification
• Motor drive bridge circuits
• Power supply load switches

Gate Driver Procurement Notes

Verify the specific suffix 'TMPX' against the manufacturer's latest datasheet to confirm the MLP-8 package variant and tape-and-reel specifications. Ensure compatibility with the target PCB footprint, as the 8-MLP package requires precise soldering techniques. Cross-reference RoHS compliance status and any recent Product Change Notifications (PCN) regarding manufacturing site or material changes before finalizing procurement orders.

Gate Driver Selection Notes

Select this component when a compact dual low-side driver with moderate 2 A drive strength is required. The inverting configuration necessitates checking signal polarity requirements against the control source. Consider the 8-MLP package constraints for thermal dissipation and board space. Compare against the FAN3226CMPX if a different package style is preferred, noting that both share similar electrical characteristics but differ in physical form factor.

Gate Driver Part Context

This part belongs to the FAN3226T series of gate drivers from onsemi. It shares core electrical specifications with variants like the FAN3226TMX-F085, which offers automotive qualification under AEC-Q101 standards. The FAN3226TMPX specifically denotes the commercial grade version in the MLP-8 package, distinguishing it from SOIC-8 alternatives or higher-current counterparts in the broader power management portfolio.

Gate Driver Replacement Considerations

The FAN3226CMPX serves as a functional alternative with identical electrical parameters but utilizes an 8-MLP package. For automotive applications requiring AEC-Q101 certification, the FAN3226TMX-F085 is the qualified substitute. Verify pinout compatibility and package dimensions before substituting.
