Hello.
We are developing a new Project with the BQ76940 IC and sometimes, when the current flows and we are measuring CC current, the BQ76940 stops the FETs and give the DEVICE_XREADY fault condition.
The I2C commands are still working and we send a status reset (0x3F) and a go to ship command (normally it is working) and the device give us the ACK but it does not go to ship mode a does not erase the fault, so we can not delete de DEVICE_XREADY bit and the unit can't work propertly.
I can delete it by disconnecting the AFE from the battery, but it is not posible ir real application (and it is not recommended in the datasheet), so, is there any way to reset the DEVICE_XREADY bit via I2C commands ?. Why the AFE replay with ACK but it does not do anything ? We have a microcontroller sending commands, but after the bit is reset, we can not close the charge or discharge FET, so the unit stop working at all.
Best regards,
Sergio.
