Isolators - Gate Drivers FAQ

What is the primary function of the desaturation detection feature?

It monitors the collector-emitter voltage of the connected IGBT to detect short-circuit conditions, allowing for rapid shutdown to protect the device.

How does the active Miller clamp improve performance?

It prevents false turn-on of the IGBT caused by high dv/dt transients during switching events by clamping the gate voltage.
