ADUM4135BRWZ

ADUM4135BRWZ is a single-channel gate driver specifically optimized for driving insulated gate bipolar transistors(IGBTs). Analog Devices, Inc., iCoupler® technology provides isolation between the input signal and the output gate drive. The ADuM4135 includes a Miller clamp to provide robust IGBT turn-off with a single-rail supply when the gate voltage drops below 2V (typical). Operation with unipolar or bipolar secondary supplies is possible, with or without the Miller clamp operation. The Analog Devices chip scale transformers also provide isolated communication of control information between the high voltage and low voltage domains of the chip. Information on the status of the chip can be read back from dedicated outputs. Control of resetting the device after a fault on the secondary is performed on the primary side of the device. Typical application includes MOSFET/IGBT gate drivers, PV inverters, motor drives, power supplies and automotive.
