PRODUCTION DATA
The internal power supply circuits have overvoltage, undervoltage, and/or current limit checks. The table below summarizes the diagnostics that apply for each power supply and the corresponding action when failure is detected.
SUPPLY | OV CHECK | UV CHECK | CURRENT LIMIT |
---|---|---|---|
DVDD | If fails, set [DVDD_OV] | If fails, digital reset | Limit current to EC table current limit specification |
CVDD | If fails, set [CVDD_OV] | If fails, digital reset, set [CVDD_UV_DRST] | Limit current to EC table current limit specification |
AVAOREF | If fails, set [AVDDREF_OV] (AVAOREF supplies AVDDREF) | If fails, device shuts down | |
AVDDREF | If fails, set [AVDDREF_OV] | If fails, set [AVAO_SW_FAIL] or digital reset | |
VIO | If fails, device losses data communication and Ping function |
