8.5.3.3.1 Overcurrent Limit (Cycle-By-Cycle)

The CBC current-limiting circuit terminates each PWM pulse limit the output current flow to the average current limit (ILIM) threshold. The overall effect on the audio in the case of a current overload is quite similar a voltage-clipping event, temporarily limiting power at the peaks of the music signal and normal operation continues without disruption on removal of the overload.

Note:

CBC (Cycle-By-Cycle) current-limiting only allows in BTL mode, not allowed under PBTL.
