Part Number: BQ76972 Tool/software: Hi,
When I do a flashdump using BQ studio 1.3.127 (or 1.3.111) of my BQ76972, the data memory is only read to 0x9327. However, balancing parameters are out of this range as one of those registers is at 0x9342 for example…

I set the output of REG1 to 5V and the output of REG2 from 0 to 1.8V. Then pull up the RST_SHUT pin for 300ms and pull down. The output of REG1 is changed from 5V to the default 3.3V, but the output of REG2 is still 1.8V. Is this due to partial reset caused by the RS…
Part Number: BQ76972 Tool/software: Hi
We need to test whether the balancing function of the chip is good in the production process. After the current balancing is opened, the voltage value collected has little change, and it is impossible to judge whether the balancing function of the chip …
