Issue Description
1
L9680CC
Deployment
Diagnostic
The high-side driver diagnostic, described in section on page
174, doesn’t work. As a consequence, the ILIM_HS_FET parameter
is not tested in production.
2
L9680CC
WSS Over
current
detection
The over current threshold doesn’t work. The user can use the
leakage to ground flag to understand if a fault condition is
present. The interface is anyway protected by means of thermal
protection.
3
L9680CC
Safing
engine
The safing records associated with CS_RS validate and process
data with matching request/response masks even if these are not
coming from CS_RS frames but from frames sniffed on
SAF_CSx.
This may lead to issues when expansion chip is used and
CS_RS frames sent on expansion are sniffed by SAF_CSx at
SBC side; the SBC fails to check its own CS_RS and therefore
all RSUs safing records CC with matching request/response
masks of expansion RSUs safing records will be updated upon
the processing of the expansion RSU SPI data.
Workaround: use two different values for WID SPI bit when
addressing CS_RS at SBC (ie WID=1) and expansion (WID=0)
side.
