The FOD8316V from ON Semiconductor is a highly integrated smart gate driver optocoupler, which is a crucial component for modern power systems. This advanced device is designed to drive IGBTs and MOSFETs in a variety of applications, such as motor drives, inverters, and power supplies. The FOD8316V provides electrical insulation between the input signal and the output power electronics, ensuring safety and noise immunity in high-voltage systems.

Features

• High Noise Immunity: Characterized by its CMR (Common Mode Rejection) of 35 kV/μs minimum at VCM = 1500 V, the FOD8316V offers excellent noise immunity, making it ideal for noisy industrial environments.
• Integrated Active Miller Clamp: An active Miller clamp is included to prevent unwanted gate turn-on, caused by Miller currents during high dv/dt switching events.
• Desaturation Detection: The device features a desaturation detection function that helps protect the IGBT/MOSFET from overcurrent conditions.
• Under Voltage Lock-Out (UVLO): With both positive-going and negative-going UVLO, the FOD8316V ensures that the gate driver is operational only when the supply voltage is adequate.
• High Insulation Voltage: The optocoupler is rated for an insulation voltage of VIORM = 1414 Vpeak, providing a robust barrier against high voltages.
