Figure 21. Balancing Tab
7.9
Fault Mask Tab
The
Fault Mask
tab, shown in
, allows the user to turn off and mask faults from various events
and select which faults trigger the active low FAULT* pin on the bq76PL455A-Q1. Faults are grouped by
type and correspond to their register locations. Further details regarding the faults and their meanings are
found in the bq76PL455A-Q1 data sheet (
).
NOTE:
Any triggered fault, if left unmasked, prevent the ability to enable balancing unless the
bq76PL455A-Q1 is set to continue balancing in the presence of a fault (by checking the
Continue on Fault
checkbox on the Balancing tab).
The
Fault Mask
tab also allows configuration of the General Purpose Input (GPI) pins to trigger faults
when they change state. This configuration is done in the
GPI Faults (check to enable)
group box in the
upper right portion of the
Fault Mask
tab.
The sample screen shot shows GPI0 and GPI1 configured such that a fault is triggered when the inputs
change from Hi to Lo (and the screen shot shows that such a transition has occurred because the GPI
fault indicator is red). In this case, since the GPI_FAULT_OUT box is checked in the
Fault Output Control
(check to enable)
group box, expect the active low FAULT* output pin of the bq76PL455A-Q1 to be low,
indicating an active fault.
