Part Number: BQ76952 Tool/software: We are noticing the battery is undergoing RESET on it's own. Upon investigating, we found out the WD (bit 4) Previous reset was caused by the watchdog timer was set.
We were testing the battery by manually enabling…
Part Number: BQ76952 Tool/software: I wanted to know if it is possible to have the input filter resistor of the cell balancing circuit to be greater than 100 ohm. In the cell balancing datasheet of BQ769x2 battery monitors, it was recommended that the…
Hi,
I did another log last night at 14V, 150mA Termination current and I sees similar results with Cell 2 and 4 reading higher than 1 and 3. But with them topping out at a safer voltage, around 3533mV.
Here are my main Questions
- is this perfectly…
Part Number: BQ76952 Tool/software: Dear TI Expert,
Our Requirement is to perform balancing through host Micro-controller.
We found sub-command in TRM.
As per our understanding we can control balancing Switches of each cell, but we are not understanding…
Part Number: BQ76952 Tool/software: Hi expert,
My customer (CosMx, Auto BMS project) found there is a passive balance issue in their project as below, please help to confirm.
They found the passive balance period sometimes would be shorter and it…
Part Number: BQ76952 Tool/software: Hello Team,
I am using BQ76952 as my AFE for voltage sensing and cell balancing. In the application note (Cell Balancing With BQ769x2 Battery Monitors) page 2, the value of the resistor range is gven between 20 -…
Part Number: BQ76952EVM Other Parts Discussed in Thread: BQ76952 Tool/software: Dear support team,
I am currently using the BQ76952 Evaluation Module as a prototype. I have connected three cells (cell 1, 2, and 16) to the test board. I configured the…
Part Number: BQ76952 Tool/software: I am designing a 32s pin balancer using BQ76952 IC. I am facing some issues while using lowside fet driver. Can you give me some reference of used architecture?
Hi Ryker,
This may be due to an odd interaction in the firmware. If having the settings equal to each other fixes the behavior, then that's good. The top cell needs to be at the cell 16 position, otherwise the internal balancing FET for it may not turn…
Part Number: BQ76952 Tool/software: Hello All, Below are my setting configuration, i have setted the time interval of balancing interval is 5 second but every time is turn on only for 500 mSec.Can please help on this.
