6.5.1
At first step, the instantaneous power in the switch is maintained to a safe level by limiting the current to the
maximum current allowed in the switch
the current flowing in the DMOS. At thermal shutdown, the device turns OFF and cools down. A restart mechanism
is used, after cooling down, the device restarts and limits the current to
the current limitation as a function of time.
