Hello
I'm using a bq35100EVM and BQStudio and I'm trying to understand the behaviour of /ALERT pin.
I have plugged the BAT+ and BAT- of my gauge on a regulated DC power supply. When I set the voltage under the low battery threshold, /ALERT output is triggered, ALERT bit from BatteryStatus register is set, and BATLOW bit from BatteryAlert register is set.
When I read all register, /ALERT output and ALERT bit come back to normal. BATLOW bit from Battery Alert register is still equal to 1.
Then I increase my voltage until it exceeds "Batlow Voltage Clear Threshold", but BATLOW bit does not clear.
According to Technical Reference : "An ALERT bit only clears if the condition for it is removed."
So is this a normal behaviour ?
Thanks by advance.
