Protection strategies on electrical faults
Multiple electrical faults may occur (intentionally or not) which are:
- Overload / Overcurrent
- Short Circuit
- Under voltage
- Over voltage
According to the type, protection strategies are applied for Pin 1, Pin 2 and Pin 4 according to the IO
configuration and on all the ports or on a single one depending on the type of issue. See table below.
