FAN5009MX

Gate Driver Overview

The FAN5009MX is a half-bridge gate driver IC manufactured by onsemi, designed for driving N-channel MOSFETs. It features two independent drivers with synchronous operation and supports both inverting and non-inverting input configurations. The device operates within a supply voltage range of 10V to 13.5V and withstands a maximum high-side bootstrap voltage of 15V. Typical rise and fall times are 40ns and 20ns, respectively. Logic thresholds are defined at 0.8V for VIL and 2.5V for VIH. It is housed in an 8-SOIC package (0.154" width) and functions across a junction temperature range of 0°C to 125°C.

Gate Driver Feature Summary

• Provides dual-channel synchronous half-bridge drive capability for efficient power switching applications.
• Supports flexible logic interface compatibility through dedicated inverting and non-inverting input pins.
• Ensures robust performance under thermal stress with an extended operating junction temperature range up to 125°C.

Gate Driver Applications

• Power factor correction circuits
• DC-DC converter topologies
• Motor control systems

Gate Driver Procurement Notes

Verify component authenticity and datasheet alignment due to the discontinued status of this part number. Confirm that the 8-SOIC package dimensions and pinout match the target PCB footprint. Ensure design specifications accommodate the specific electrical characteristics of the legacy component rather than assuming equivalence with newer generations.

Gate Driver Selection Notes

Select this component when a reliable half-bridge driver with distinct inverting and non-inverting inputs is required. The synchronous drive configuration simplifies control logic compared to asynchronous alternatives. Consider the 15V bootstrap limit and 10V-13.5V supply range during circuit design to ensure proper gate drive voltage levels for the connected N-channel MOSFETs.

Gate Driver Part Context

The FAN5009MX belongs to the FAN5009 series of gate drivers from onsemi. This series focuses on providing isolated or floating gate drive solutions for power electronics. The MX suffix indicates the specific tape-and-reel packaging format and the 8-SOIC physical package variant used for surface-mount assembly.

Gate Driver Replacement Considerations

This product is officially discontinued. No direct public substitute part numbers are confirmed in the provided documentation. Designers must evaluate alternative half-bridge drivers from current onsemi portfolios or other manufacturers, ensuring compatibility with the existing 8-SOIC footprint and electrical requirements.
