45 / 104 page  Table 25. PR/PF leakage diagnostics Fault type Assertion condition IC reaction to assertion Release condition IC reaction to flag clear Maskable PF STG If the VRCM current exceeds ILEAK_SOURCE_TH for an interval longer than tVRCM_LEAK_FLT, the PF_STG fault is acknowledged The PF_STG flag is set FAULTN line is asserted Diagnostic routine is stopped at the end of the leakage step Cyclic diagnostic triggers are inhibited The PF_STG flag can always be cleared on read FAULTN line is released Cyclic diagnostic triggers are unmasked LEAK_EN = 0 masks cyclic diagnostic trigger (but not the on-demand one) PF_PR_STB_STG_FAULTN_MSK masks fault redirection on FAULTN pin PF STB If the VRCM current exceeds ILEAK_SINK_TH for an interval longer than tVRCM_LEAK_FLT, the PF_STB fault is acknowledged The PF_STB flag is set FAULTN line is asserted Diagnostic routine is stopped at the end of the leakage step Cyclic diagnostic triggers are inhibited The PF_STB flag can always be cleared on read FAULTN line is released Cyclic diagnostic triggers are unmasked LEAK_EN = 0 masks cyclic diagnostic trigger (but not the on-demand one) PF_PR_STB_STG_FAULTN_MSK masks fault redirection on FAULTN pin PR STG If the VRCM current exceeds ILEAK_SOURCE_TH for an interval longer than tVRCM_LEAK_FLT, the PR_STG fault is acknowledged The PR_STG flag is set FAULTN line is asserted Diagnostic routine is stopped at the end of the leakage step Cyclic diagnostic triggers are inhibited The PR_STG flag can always be cleared on read FAULTN line is released Cyclic diagnostic triggers are unmasked LEAK_EN = 0 masks cyclic diagnostic trigger (but not the on-demand one) PF_PR_STB_STG_FAULTN_MSK masks fault redirection on FAULTN pin PR STB If the VRCM current exceeds ILEAK_SINK_TH for an interval longer than tVRCM_LEAK_FLT, the PR_STB fault is acknowledged The PR_STB flag is set FAULTN line is asserted Diagnostic routine is stopped at the end of the leakage step Cyclic diagnostic triggers are inhibited The PR_STB flag can always be cleared on read FAULTN line is released Cyclic diagnostic triggers are unmasked LEAK_EN = 0 masks cyclic diagnostic trigger (but not the on-demand one) PF_PR_STB_STG_FAULTN_MSK masks fault redirection on FAULTN pin L9965P Functional description DS14702 - Rev 4 page 45/104 |
