SLUUCF2C January 2021 – May 2022 BQ769142
The BQ769142 device implements a periodic check on the input mux for the hardware protection comparator subsystem used for the OV, UV, OCC, OCD1, and OCD2 primary protections. If this check fails, it can trigger a Protection Comparator MUX Permanent Fail (HWMX) and disable the battery pack. This PF can be enabled by setting the Settings:Permanent Failure:Enabled PF C[HWMX] and Settings:Manufacturing:Mfg Status Init[PF_EN] configuration bits.
