Part Number: BQ76972 Other Parts Discussed in Thread: BQ76952 , Tool/software: Hello Alex/team,
We have been using Bq76952 and recently wanting to switch to Bq76972 since they are exactly same and 972 comes with a better precision.
So, wanted to know how…
Part Number: BQ76972 Tool/software: There is a sentence in chapter 7.8.7 of the datasheet that I must admit I don't understand.
Note: when the selected pin is deasserted, the respective FET will only be enabled if there are no other items blocking…
Part Number: BQ76972 Tool/software: If I look at the pin equivalent diagram ( SLUAAF2 – MAY 2021) for this pin it seems it clamps it to VSS when turning off the FET. Is this true?
Why is it different from the CHG pin?
This will draw a high current…
Part Number: BQ76972 Other Parts Discussed in Thread: BQ76952 , , BQ76952EVM Tool/software: Hello,
In Section 4.10 Cell Voltage Measurement Accuracy of the TRM for the BQ76972, there are tables listing offsets that the host CPU must apply to the voltage…
Part Number: BQ76972 Tool/software: Hi team,
e2e.ti.com/.../bq76952-question-about-buffer-length
I want read data memory with checksum, and I found a e2e which has talked about 0x61 data length ---When reading from the data memory, the transfer buffer…
Part Number: BQ76972 Tool/software: A shift on the CS pin when using SPI can wake the device but is there a similar function using I2C or do I need an extra signal for that?
Part Number: BQ76972 Tool/software: I want to use BQ76972 for low side switching circuit. The reference manual does not specify , will it be mandatory to use external FET Driver IC for low side switching??
Hi Alexis, hope you had great days!

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…
Part Number: BQ76972 Other Parts Discussed in Thread: BQ76952 Tool/software: Hi expert,
I've noticed the Section 9.2 & 9.3 of the Technical Reference Manual is talking about the I2C and SPI of the BQ76972. May I know if there is any reference…
