Part Number: BQ41Z90 Hello,
in the BQ41Z90 datasheet I found that SRP, SRN input ranges are -0.25V to 0.5V. However, the ADC 18-bit input range is not specified.
Is the ADC voltage range -0.25V to 0.5V as well?
Thanks in advance!

Part Number: BQ41Z90 Hello,
In my design, using the BQ41Z90, I'm thinking about the power MOSFETs arrangement.
Architecture wise, the charge and discharge MOSFETs will be placed in series; hence, we'll have a single charge/discharge line.
Now, I…
Part Number: BQ41Z90 Hello,
I'm investigation the cell balancing capabilities of BQ41Z90.
From datasheet I see that the IC supports up to 50mA bypass current per cell (100mA absolute max rating).
However, I also see that the internal FET RDS_on…

Part Number: BQ41Z90 Hello,
I'm trying to understand how the Discharge FET Permanent Fail (page 31 on the BQ41Z90 Technical Reference Manual) is triggered. From the manual I see that it's current based. If some current can be pulled when the FET command…
Part Number: BQ41Z90 Hi TI Team,
I noticed that the BQ41Z90 EVM board has an SPI/UART connector populated. However, I cannot find any SPI/UART description in the BQ41Z90 datasheet or TRM.
May I confirm:
Does the presence of the SPI/UART interface…
