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
respective output (OUT

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

Open load detection in Off mode
It is possible for the microcontroller to detect an open load condition by adding a simply
resistor (for example, 10k ohm) between one of the outputs of the bridge (for example,
