Shahab,
If BQ part is problem then I may not be able to help. I am checking the TPS25750 looks to be doing things correctly and writing to BQ25792 correctly. Once you provide read-back details I will confirm
Thanks,
Chris
Part Number: BQ77915 Hello, in my project I use two BQ7791500 6S LiPo battery BMS (3 cells on each BQ7791500).
During tests, I found an anomalous behavior of the BMS.
When the battery voltage is lower than 23.8 V and I put PRES pin high, both charge and…
Part Number: BQ77915 Other Parts Discussed in Thread: BQ76942 My design consists of a 10S li-ion battery pack. The power distribution is seperated between the top 5 cells and the bottom 5 cells. The discharge is uneven between the top and bottom, with…

Hi team,
I use BQ77915 08 for my 4S2P Li ION battery.. I'm testing error conditions.
For protection, I set my current limit according to 50mR resistance.
According to datasheet;
OCD1 = 70mV / 50mR = 1.4A
OCD2 = 140mV / 50mR…
Part Number: BQ77915 Hello,
We are having difficulty getting this part to work when we have a significant imbalance in cell voltages. Currently we have one part and 4 series batteries. Current issue is when the cells are imbalanced, the discharge fet…
Part Number: BQ77915 Hey guys,
The BMS designs have been testing well
As you suggested, i followed the BQ77915EVM and added capacitors in parallel to the MOSFETS and between PACK- and PACK+ for ESD Protection
Are TVS diodes a necessary upgrade ? Do…
Part Number: BQ77915 Hello,
I'm using BQ7791500PW. A problem when resuming from HIBERNATE mode when the battery cells are fully charged.
When +PACK and -PACK are connected to the charger, the PRES circuit is completed by +PACK.
The charger, built…

Hi Everyone
I am using a BQ7791508 on a board with a 5s battery for protection and cell balancing. The board also has a charger based on the BQ24610. When I was testing the board for the first…
