FAN3216TMX-F085

Gate Driver Overview

The FAN3216TMX-F085 is a dual low-side gate driver designed for N-channel MOSFETs, manufactured by onsemi. It operates within a supply voltage range of 4.5V to 18V and delivers peak output currents of 3A at VDD=12V. The device features TTL-compatible input thresholds with hysteresis, ensuring reliable logic interfacing. Internal propagation delay matching between channels is maintained within 1ns, facilitating precise timing for synchronous rectification applications. Packaged in an 8-SOIC surface-mount configuration, it supports high-speed switching with typical rise and fall times of 12ns and 9ns respectively under a 1nF load.

Gate Driver Feature Summary

• Dual channel architecture optimized for driving N-channel enhancement mode MOSFETs in low-side switch configurations.
• Integrated undervoltage lockout (UVLO) circuitry maintains outputs low during power-up sequences until supply voltages reach operational levels.
• TTL input threshold compatibility allows direct interfacing with standard logic controllers independent of the drive supply voltage.

Gate Driver Applications

• Synchronous rectifier control in DC-DC converters
• Low-side switching for N-channel MOSFET arrays
• High-speed power management circuits requiring matched channel timing

Gate Driver Procurement Notes

Verify the specific suffix F085 corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 8-SOIC package dimensions align with the designated PCB footprint and thermal relief requirements. Ensure the operating temperature range specifications meet the environmental constraints of the final application design.

Gate Driver Selection Notes

Select this component when dual low-side driving capability is required for N-channel MOSFETs with moderate current demands. The internal propagation delay matching makes it suitable for applications where phase alignment between two switches is critical. Consider the 4.5V to 18V supply range compatibility with available system power rails before integration.

Gate Driver Part Context

This part belongs to the FAN321x series of high-speed gate drivers from onsemi. It shares architectural similarities with the FAN3217 but differs in specific electrical characteristics and intended bridge configurations. The series focuses on providing robust driving capabilities for power electronics while maintaining compact surface-mount packaging for space-constrained designs.

Gate Driver Replacement Considerations

The FAN3217TMX_F085 is a documented alternative within the same family, though it may differ in bridge type configuration. Verify pinout compatibility and electrical parameter equivalence before substitution. No other direct cross-model substitutes are confirmed in public documentation.
