FAN3225CMX

Gate Driver Overview

The FAN3225CMX is a dual low-side MOSFET gate driver manufactured by onsemi, housed in an 8-SOIC surface-mount package. It operates within a supply voltage range of 4.5 V to 18 V and delivers peak output currents of 5 A for both sourcing and sinking. The device features independent inverting and non-inverting inputs, with typical rise and fall times of 12 ns and 9 ns, respectively. Designed for robust performance, it functions across an extended temperature range from -40°C to +125°C. This component is classified under PMIC gate drivers and utilizes silicon technology.

Gate Driver Feature Summary

• Dual independent channel configuration supporting simultaneous control of two low-side MOSFETs
• Integrated logic compatibility allowing direct interface with standard TTL or CMOS control signals
• High current drive capability designed to minimize switching losses in power applications

Gate Driver Applications

• DC-DC converter circuits requiring efficient low-side switching
• Motor control systems utilizing MOSFET-based topologies
• Power supply designs needing isolated or complementary gate drive signals

Gate Driver Procurement Notes

Verify the specific suffix 'CMX' against official datasheets to confirm the 8-SOIC packaging variant. Confirm RoHS compliance status through manufacturer declarations. Check for End-of-Life notices as availability may be restricted. Ensure input signal levels match the specified logic thresholds before integration.

Gate Driver Selection Notes

Select this component when dual low-side driving with high peak current is required. Compare rise and fall times against system switching frequency requirements. Verify that the 8-SOIC package fits the PCB layout constraints. Consider thermal dissipation capabilities relative to the expected duty cycle and ambient temperature conditions.

Gate Driver Part Context

This part belongs to the FAN3225C series of gate drivers. It shares functional similarities with other low-side drivers but is distinguished by its dual-channel architecture and specific SOIC footprint. It serves as a solution for applications requiring compact, high-performance switching control without the complexity of half-bridge configurations.

Gate Driver Replacement Considerations

Check for pin-compatible alternatives within the same family. Verify that substitute parts offer equivalent peak current ratings and propagation delays. Ensure the replacement supports the required operating voltage range and temperature specifications.
