Dear Sir / Madam,
We are using the alert signal to turn off our load when the battery voltage drops below a set level.
Only the BATLOW register is used to trigger the alert signal.
Alert configuration 0x1000
LED configuration 0x00
Cell BL set volt threshold 2750
Cell BL set volt time 2
Cell BL clear volt threshold 3500
The gauge works until we remove the battery. After reconnecting the battery alert signal is gone.
Cycling the battery, resetting the device, recalibrating, sending different commands does not help.
The only method that worked was writing the standard firmware and then overwriting it with a saved golden image.
The battery is not connected during shipping. Is there a simpler way to activate the Alert signal without rewriting the Firmware?
Thanks,
Marcus
