Part Number: BQ79656-Q1 what could be the reason why the bq79656 is suddenly stop giving response to MCU even if there is a request from the MCU. what need to be done to get the response from the bq79656.
Part Number: BQ79656-Q1 Other Parts Discussed in Thread: BQ79600-Q1 Tool/software: Dear Team
1. What happens if we update the cell balancing timers before expiration and send the Go Command?
2. Suppose I write three cells' cell balancing timers with…
Part Number: BQ79656-Q1 Hi TI Team,
Currently i am using the BQ79656-Q1 IC for AUTOMOTIVE BMS application. We are giving 56 volt at BAT pin. But at LDOIN pin we get only 4.1V. At NPNB pin 4.7 volt is present. We are using 330ohm resistance at collector…
Part Number: BQ79656-Q1 I want to implement passive cell balancing using this part, but I am not able to find information whether the pins can support powering an external mosfet. By the block diagram It is very obvious. But still want to get a confi…

Hi,
I'm working with a setup where 8 boards are connected and the BQ79600 is used as the bridge IC. Initially all data readings (voltage, temperature, etc.) from the BQ79656 are correct. However, after some…
Part Number: BQ76200 Other Parts Discussed in Thread: BQ79656-Q1 , BQ79758-Q1 , , BQ76952 , BQ76940 Tool/software: Hi, I am trying to design a BMS with active cell balancing. TI team suggested BQ79656-Q1 (16S, 4th gen, does not require NDA for evaluation…
Hi Quentin,
I understand we need 500us blanking time for adding margin.
Quentin Silic said: Just do not configure it for cell balancing. Keep the CB_TIME at 0.
>> There is no CB_TIME register on BQ79656. Was I below correct?

Our BMS system consist of BQ79656-Q1 as base device and six BQ79616-Q1 devices.
We have connected HV battery with shunt current sensing, charge-discharger and contactors.
There…
Part Number: BQ79656-Q1 Tool/software: Hi,
I am using a Custom board Bq79656-q1. Following is my progress
1. I can wake the device from Shutdown to Active Mode
2. I can turn on TSREF LDO by broadcast Write
So I think there is no issue with my…
Part Number: BQ79656-Q1 Hi TI team, Since all cells voltage measurements are muxed to main and AUX ADC, how could cell measurement and current measurement to synchronize? Is that just one cell to current or all cells to current? Thanks Wei
