Other Parts Discussed in Thread: BQ26220 , BQ27010 , BQ27000 , BQ2013H , BQ2016 , BQ2014H , BQ2060A I am designing a NiMH battery pack (6 series connected cells) that requires a gas gauge / monitor.
I was planning on using the BQ26220 monitor (HDQ and a GPIO…
Other Parts Discussed in Thread: BQ26220 Will the BQ26220 accurately measure coulombs, with currents out of the battery in the 16 to 100uA range, but having occasional 20mS pulses of up to 300mA. The high current pulses occur over a period of 100mS when a DC…
Me too. I have the same problem. I'm using msp430g2553 with battery monitor bq26220.
I put the pull up resistor 10k for HDQ wire.
When I try to debug from msp430 to bq26220, the code stops in function HDQBreak();
Could it be a software problem?
Could…
Hello,
To calculate the capacity of your battery you need to take the velue in the DCR register and the value in the DTC register.
In the datasheet of the BQ26220 you can see that the DCR counts at a rate equivalent to one count per 3.05μVH. And in the…

Other Parts Discussed in Thread: BQ27010 , BQ26220 Hello
Has anyone used a bq27010 as a gas gauge for a NiMH battery pack?
We were going to use a bq26220 as a monitor for a 6cell NiMH battery pack. dMax suggested we use a bq27010 as the monitor.
We…

Good Morning,
I am working on BMS that's requires high coulometric measurement accuracy, two battery IC monitor devices (Bq27010) and Bq26220 (21)) sould be implemented. I would like to…
Other Parts Discussed in Thread: BQ2060A , BQ26500 , BQ26501 Hello Everybody,
I am designing a new DC-UPS with external batteries, and I'd like to keep track of their SOC. Some of those batteries (LiFePO4, LiCoO2) will have a BMS with integrated bq4…
