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
respective output (OUT
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 will enter in stby mode as soon as the fault is cleared.
Reverse battery protection
Three possible solutions can be considered:
1.
2.
3.
The device sustains no more than -30A in reverse battery conditions because of the two
body diodes of the power MOSFETs. Additionally, in reverse battery condition the I/Os of
