45 ms) than the POWER DOWN signal (P.DN).
When the POWER DOWN interrupt occurs, there is no way of knowing whether it is due to Medium Mains Interruptions or due to shutdown. Hence, there is no choice but to initiate shutdown procedure as described further below. The definition of Mains Interruption is given below: • Short Mains Interruptions. Duration of the interrupts
