Part Number: BQ27426 Hi Team,
I am working on BQ27426 fuel Guage. The learning cycle has been completed and I have got the golden learning images in .fs file format. I am new to working in TI based fuel gauges. I wanted to know the steps that I should…
Part Number: BQ27426 Hello,
Fuelgauge system side application, Load Mode/select uses the default 0x81.
Present average discharge power:
1、Present average discharge power, how often is it averaged?
2、When do I start averaging? 3、If the discharge time does…
Hello Dominik,
Background of the question:
Since the discharge current requirement of Bq27426 is >C/10, but the discharge current in our application does not always satisfy >C/10, and the average current does not satisfy >C/10, we would like to make the…
Part Number: BQ27426 Used a new battery, the voltage flat area in Chem Data ranges from 3679mV to 3803mV after performing gold learning.
During the gradual aging of the battery 1, FCC will decrease, the voltage range of the flat area of the battery, will…
Part Number: BQ27426 Hello,
Qmax does not require frequent updates during battery life.
1、What is the basis for Qmax not being updated frequently?
2、How long can I allow Qmax to not update?
3、At what % of battery aging can Qmax not be updated and can…
Part Number: BQ27426 Hello,
Qmax update rules.
1, The battery temperature is between 10-40℃;
2, One charge/discharge exceeds Qmax*37%;
3, Battery voltage is not in flat area.
Do the temperature rules have to be satisfied during charging/discharging as…
Part Number: BQ27426 hello,
Qmax:
1、One-time charging power=Qmax*37%+1mAh
2、Battery temperature is between 10-40℃.
3、Battery voltage is not in flat area
RA:
1、Discharge charge crosses a grid point
2, Discharge current = C/10
What is the error between…

Part Number: BQ27426 Hi expert,
Customer found the registers would be cleaned and become default after entering then exiting sleep mode. Not sure when the POR happened cause they read out the [ITPOR] after exiting sleep.

Hello,
1, What is the purpose of the VatChgTerm register? Is it similar to reserve capacity?
2、Capacity between VatChgTerm to Terminal Voltage = Fuelgauge.FCC. Is the understanding correct?
3, How is VatChgTerm related to DODatEOC…
