The ADuM4135 is a single-channel gate driver specificallyoptimized for driving insulated gate bipolar transistors (IGBTs).Analog Devices, Inc., iCoupler® technology provides isolationbetween the input signal and the output gate drive.
The ADuM4135 includes a Miller clamp to provide robustIGBT turn-off with a single-rail supply when the gate voltagedrops below 2 V. Operation with unipolar or bipolar secondarysupplies is possible, with or without the Miller clamp operation.
The Analog Devices chip scale transformers also provideisolated communication of control information between thehigh voltage and low voltage domains of the chip. Informationon the status of the chip can be read back from dedicatedoutputs. Control of resetting the device after a fault on thesecondary is performed on the primary side of the device.
Integrated onto the ADuM4135 is a desaturation detectioncircuit that provides protection against high voltage shortcircuitIGBT operation. The desaturation protection containsnoise reducing features such as a 300 ns masking time after aswitching event to mask voltage spikes due to initial turn-on.An internal 500 µA current source allows low device count andthe internal blanking switch allows the addition of an externalcurrent source if more noise immunity is needed.
The secondary UVLO is set to 11 V with common IGBTthreshold levels taken into consideration.
