1. 0.5C is recommended, but using 1C charging will not affect the results for learning. I have recently published an updated learning cycle app note specifically for the bq40z80, but it also applies to the…
Hi Darshil,
Why would you want to use a non-TI battery monitoring IC? ;)
I think this should be possible, but you would incur additional voltage drop as a result.
Some other options depending on the number of cells needed in the application:

Part Number: BQ40Z50-R2 Other Parts Discussed in Thread: BQ40Z50 , BQ40Z80 , BQ34Z100 Hi,
When BQ40Z50-R2 is adopted in 4s32p, what is expected concern?
Cell capacity is 100000mAh and charging/discharging current is 2~3A.
Thanks.
Hello Jack,
Oddly enough, I actually found the description of this bit in the Technical Reference Manual for the BQ40Z50-R2 in Section 6.2 .
It is odd that this is not also in the TRM for the BQ40Z80-R3 . Let me know if the description was enough…
Hi Renan,
You can adjust the temperature trip points by changing the resistor network attached. The temperature thresholds in the BQ77915 data sheet are a ratio. The part sees a resistor ratio of VTB determine by RTS_PU/(RTS_PU + RTS). You can adjust…
Part Number: BQ40Z80EVM-020 Other Parts Discussed in Thread: BQ40Z80 , BQSTUDIO Hello,
I am using the bq40z80 eval board for testing purposes before developing my own BMS board. So my actual battery configuration is 6s li-ion battery pack according…
Hi Joshi,
Unfortunately, there is not a device that meets this exact description. Battery protectors typically are placed inside the battery pack and they do not have the ability to detect full charge or whether charging is taking place. Here are some…
Hi Wyatt,
Ok, that's really good to know! That would explain the problem that I'm having working with this charger (my application is required to be compatible with it).
The charger tends to keep the clock line high for ~90-95 us during a repeated…
Hello Jake,
Aha, I see. The bq40z80-R2 EVM does not support the GDK automated cycling. I'm going to start a thread with you and an apps engineer here in Dallas for the automation of equipment.
Part Number: BQ40Z80EVM-020 Other Parts Discussed in Thread: BQ40Z80 Tool/software: Hi team,
Could you help to check why an error occur when I programming chemistry in BQ40Z80EVM. Error code is 1470.
The EVM is powered by DC source 20V in pack+ pack…
