hello,
i'm involved in a design where the reporting of the remaining capacity of the used battery is vital. So i've decided for this purpose to use a system gas gauge bq27510-g3.
I've understood mostly the function of the chip but i'm in doubt with the measurement of the standby current, respectively with the min. value of it. When our device is in OFF state the current consumption is less than 1 mA (ca. 300uA) from the battery. Because the device can remain in this state for a long time of period (i.e. 2 or 3 months) this fact can not be leave unconsiderated. I saw in the datasheet that a "deadband" value can be set in a range from 0 to 255.
If i set the deadband value on "0", will the bq27510 measure the OFF state current flow correctly?
How is the right dealing actually with this behaviour?
Thanks in advance for your help.
Alexandru
