FAN3228TMX-F085

Gate Driver Overview

The FAN3228TMX-F085 is a dual low-side MOSFET gate driver manufactured by onsemi. It operates within a supply voltage range of 4.5V to 18V and provides independent inverting and non-inverting outputs. The device delivers peak source and sink currents of 3A each, with typical rise and fall times of 12ns and 9ns respectively. It is housed in an 8-SOIC package (0.154" width) and supports an operating temperature range from -40°C to +125°C.

Gate Driver Feature Summary

• Dual-channel architecture providing independent inverting and non-inverting logic inputs for flexible control configurations.
• High-speed switching capability with nanosecond-level propagation delays to minimize power loss during transitions.
• Robust output stage capable of sourcing and sinking 3A peak current to rapidly charge and discharge MOSFET gates.

Gate Driver Applications

• Low-side switching in DC-DC converter topologies
• Motor control circuits requiring high-current gate drive
• Industrial power management systems

Gate Driver Procurement Notes

Verify the specific suffix F085 against the manufacturer's latest datasheet to confirm pinout and electrical specifications match your design requirements. Confirm lead-free status and RoHS compliance through official documentation before integration. Check for end-of-life notices or alternative recommendations directly from onsemi channels.

Gate Driver Selection Notes

Select this component when a dual low-side driver with asymmetric input logic (inverting/non-inverting) is required. Ensure the application demands 3A peak drive current and operates within the 4.5V to 18V supply range. Verify that the 8-SOIC package dimensions fit the PCB layout constraints and thermal requirements.

Gate Driver Part Context

This part belongs to the FAN322x series of high-speed gate drivers from onsemi. It shares the same functional family as variants like the FAN3227 and FAN3229 but is distinguished by its specific combination of dual low-side topology, 3A drive strength, and mixed inverting/non-inverting input configuration.

Gate Driver Replacement Considerations

Consult onsemi documentation for direct replacements. Potential alternatives within the same series include FAN3227TMX-F085 or FAN3229TMX-F085, provided their specific input logic and drive current characteristics align with the original design intent.

Gate Driver FAQ

What is the difference between the two inputs of the FAN3228?

The FAN3228 features one inverting input and one non-inverting input, allowing for complementary control signals without external inversion circuitry.

Is the FAN3228 suitable for high-frequency applications?

Yes, it offers typical rise and fall times of 12ns and 9ns, supporting high-frequency switching operations common in modern power electronics.
