FAN7380MX

Gate Driver Overview

The FAN7380MX is a monolithic half-bridge gate driver IC from onsemi, designed for driving MOSFETs and IGBTs. It features two independent drivers in an 8-pin SOIC package. The device operates with a supply voltage range of 10V to 20V and supports logic inputs compatible with 3.3V and 5V systems (VIL: 0.8V, VIH: 2.5V). It delivers peak output currents of 90mA sink and 180mA source. Typical switching times are 230ns rise and 90ns fall. The junction temperature range is -40°C to 150°C, with an operating ambient temperature up to 125°C. Maximum high-side voltage is 600V.

Gate Driver Feature Summary

• Monolithic half-bridge configuration for synchronous drive applications
• Compatible with standard logic levels including 3.3V and 5V inputs
• Capable of driving N-channel MOSFETs and IGBTs up to 600V
• Integrated bootstrap diode for high-side gate drive

Gate Driver Applications

• Motor control systems
• Power supply circuits
• Inverter topologies

Gate Driver Procurement Notes

Verify the specific suffix 'MX' corresponds to the tape and reel or cut tape packaging requirements for your assembly line. Confirm that the 8-SOIC footprint matches your PCB design constraints. Ensure the 10V-20V VCC range aligns with your system's power rail availability. Check RoHS compliance status if required by your manufacturing standards.

Gate Driver Selection Notes

Select this component when a compact half-bridge solution is needed for medium-power MOSFET or IGBT switching. The 180mA source current is suitable for small-to-medium sized devices. Consider thermal dissipation limits of 625mW in your layout. Compare against higher current alternatives like the FAN7390MX if faster switching or larger gates are required.

Gate Driver Part Context

The FAN7380MX belongs to the FAN7380 series of half-bridge gate drivers. It is part of onsemi's portfolio of power management ICs focused on efficient motor and power conversion control. The device simplifies circuit design by integrating both high-side and low-side drive functions into a single small-outline package.

Gate Driver Replacement Considerations

The FAN7380M is a related variant in the same series, often available in tube packaging instead of tape and reel. Verify pinout compatibility before substitution. Other family members like the FAN73832 offer different current capabilities but may require different supply voltages or configurations.
