Part Number: BQ76940
I have BMS design using bq78350-R1 + bq76940, LFP 15S configuration.
I have observed strange frequency noise from the cell at top and bottom of each ADC bank of bq76940.
such as CELL #5, CELL #6, CELL #10, CELL #11 only,
Not on CELL #1 or CELL #15 or others,
Noise level is various some channel is 30~50mV, some channel up to 200mV.
I have attached some graphs,
Can I get any advice about such a problem ?
Thanks
P/S : I have designed similar with EVM design from TI
