            ADuM4135/ADuM4136 Single and Dual IGBT Gate Drivers
                    Analog Devices offers its ADuM4135/ADuM4136, high-voltage, insulated gate bipolar transistor gate drivers featuring iCoupler®  technology
    

Image of Analog's ADuM4135 Miller Clamp ADI's ADuM4135 and ADuM4136 are single-channel gate drivers specifically optimized for driving insulated gate bipolar transistors (IGBTs). Its iCoupler technology provides isolation between the input signal and the output gate drive.

The ADuM4135 includes a Miller clamp in order to provide robust IGBT turn-off with a single rail supply once the gate voltage drops below 2 V. Operation with unipolar or bipolar secondary supplies is possible with or without the Miller clamp operation.

Integrated into the ADuM4135 and ADuM4136 are desaturation detection circuits that provide protection against high-voltage, short-circuit IGBT operation. The desaturation protection contains noise-reducing features such as a 300 ns (ADuM4135) and 314 ns (ADuM4136) masking time after a switching event to mask voltage spikes due to initial turn-on. An internal 500 µA (ADuM4135) and 537 µA (ADuM4136) current source allows for a low part count, but the internal blanking switch allows for the addition of an external current source in case more noise immunity is desired.
