Single 2A High-Speed, Low-Side IGBT Driver

The FAN3181 is suitable for designed to stand-alone IGBT driver in lowside switching applications by providing high peak current pulses duringthe switching intervals. The protection functions include Under-Voltage Lockout (UVLO) and Over-Current Protection (OCP), and Desaturation Protection (DESAT) with fault-out function and active miller clamp function. An open-drain fault-out signal is provided to indicate that an over-current, under-voltage, and Desaturation detect has occurred. Softturn-off feature is used to increase the reliability of an application during short-circuit or over-current periods. This feature works after the desaturation or over-current protection is activated, which provides protection for IGBT against short-circuit and over-current events. With the “Soft” turn-off feature, the gate voltage will be reduced slowly in order to reduce IGBT current.
