ADUM4138 IGBT Gate Drivers

Analog Devices ADUM4138 IGBT Gate Drivers include an isolated flyback controller, allowing simple secondary voltage generation. The ADUM4138 integrates overcurrent detection protecting the IGBT in case of desaturation and/or overcurrent events. The overcurrent detection is coupled with a high-speed, two-level turn-off function as protection against faults. The device offers a low gate voltage detection circuit which triggers a fault if the gate voltage does not rise above the internal threshold within the time allowed after turning on (12.8μs typical). IGBT device failures that exhibit gate shorts or other causes of a weak drive are detected through the low-voltage detection circuit.
