Electrical specifications

L9380

8/18

Function is given for supply voltage down to 5.5V.

Function means: the channels are controlled from the inputs, some other parameters may

exceed the limit. In this case the programming voltage and timer threshold will be lower. This

leads to a lower protection threshold and time.
