FAN3227TMX

Gate Driver Overview

The FAN3227TMX is a dual high-speed low-side MOSFET gate driver manufactured by onsemi. It features two non-inverting drivers with a peak output current of 2 A. The device operates within a supply voltage range of 4.5 V to 18 V and utilizes an MLP-8 surface-mount package. Key timing parameters include a rise time of 12 ns and a fall time of 9 ns. It supports a wide operating temperature range from -40°C to +125°C, with a quiescent supply current of 750 uA and power dissipation of 460 mW.

Gate Driver Feature Summary

• Dual-channel architecture providing independent control for two low-side switches
• High-speed switching capability with nanosecond-level rise and fall times
• Robust thermal performance supporting operation up to 125°C junction temperature

Gate Driver Applications

• DC-DC converter circuits requiring synchronous rectification
• Motor drive systems utilizing low-side MOSFET configurations
• Power supply modules needing efficient gate control for power stages

Gate Driver Procurement Notes

Verify the specific package variant, as the base model may correspond to different physical footprints such as MLP-8 or SOIC-8 depending on the suffix. Confirm RoHS compliance status and automotive qualification requirements if applicable to the target application environment before finalizing procurement orders.

Gate Driver Selection Notes

Select this component for applications requiring precise low-side switching with moderate current drive capabilities. Ensure the input logic levels are compatible with the controller interface. Consider the thermal constraints of the MLP-8 package when designing the PCB layout for adequate heat dissipation under continuous load conditions.

Gate Driver Part Context

This part belongs to the FAN3227T series of gate drivers designed for general-purpose power management applications. It serves as a cost-effective solution for driving MOSFETs in compact power electronics designs where space efficiency and switching speed are prioritized over high-current bridge configurations.

Gate Driver Replacement Considerations

The FAN3227CMX_F085 offers similar electrical characteristics but utilizes an SOIC-8 package instead of the MLP-8 footprint. Verify pinout compatibility and thermal resistance differences when substituting between these package variants.
