PRODUCTION DATA
When the converter starts up, the BQ25720 reads CELL_BATPRESZ pin configuration and sets ChargeVoltage() and SYSOVP threshold (1s – 6 V, 2s – 12 V, 3s/4s – 19.5 V ). Before ChargeVoltage() is written by the host, the battery configuration will change with CELL pin voltage. When SYSOVP happens, the device latches off the converter. Fault SYSOVP status bit is set to 1. The user can clear latch-off by either writing 0 to the Fault SYSOVP status bit or removing and plugging in the adapter again. After latch-off is cleared, the converter starts again.
