The fault conditions are:

Possible origins of fault conditions may be:

When a fault condition is detected, the user can know which power element is in fault by
monitoring the IN
In any case, when a fault is detected, the faulty leg of the bridge is latched off. To turn-on the

Behavior in fault condition (how a fault can be cleared)
In case of the fault condition is not removed, the procedure for unlatching and sending the
device in Stby mode is:
- Clear the fault in the device (toggle: INA if ENA=0 or INB if ENB=0)
- Pull low all inputs, PWM and Diag/EN pins within tDEL.
If the Diag/En pins are already low, PWM=0, the fault can be cleared simply toggling the
input. The device enters in stby mode as soon as the fault is cleared.
