Analog Devices, Inc.
, iCoupler® technology provides isolation between the input signal and the output gate drive.
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 the dedicated fault outputs.
The ADuM4137 provides isolated fault reporting for overcurrent events, remote temperature overheating events, undervoltage lockout (UVLO), and thermal shutdown (TSD).
Integrated onto the ADuM4137 is an overcurrent detection feature that protects the IGBT in case of overcurrent events.
The split emitter overcurrent detection is coupled with a high speed, two-level turn off in case of faults.
The ADuM4137 provides a Miller clamp control signal for the external metal-oxide semiconductor field effect transistor (MOSFET) to provide robust IGBT turn off with a single rail supply when the gate voltage drops...
