Is there overload protection in the ADuM5x1x and ADuM6x1x?


Yes – These devices contain a Thermal shutdown circuit that turns off the tank
oscillator if the temperature rises to 150C.  The Thermal Shutdown circuit has
about 10C of hysteresis so the temperature must drop 10C before the part
automatically restarts. If the fault that caused the overload persists, then it
will cycle on and off until the fault is removed. We chose to implement a
thermal shutdown rather than a current limit because it takes ambient operating
temperature into account shutting off the part at lower output power at high
ambient temperature.
