JAJSL33A june 2020 – january 2021 BQ25731
PRODUCTION DATA
When the converter starts up, the BQ25731 reads CELL_BATPRESZ pin configuration and sets ChargeVoltage() and SYSOVP threshold (1s – 6 V, 2s – 12 V, 3s/4s – 19.5 V and 5s – 25 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.
