Part Number: BQ76942 Hi,
I am going to use the SPI of BQ7694203 IC and the communications should be done in a 5V level. I am planning to use the REG1 of BQ7694203, for which the datasheet suggests that the REG1 is automatically enabled to 5.5V in the device…
Part Number: BQ76942 Hi,
We are seeing a weird voltage measurement on Cell 8 and 9 on Registers where our gg. file only goes up to Cell 7. This happens right after we are calibrating the temperatures. This isn't too much of a problem if it is an anomaly…
Part Number: BQ76942 Hello,
I was hoping to get some clarity on choosing resistors for the PACK and LD pins. As I understand it, these pins are for voltage sensing and don't have significant input currents. The evaluation board uses two 5.1k resistors…

Greetings,
Related to this topic , but having more narrowed down question.
Does the BQ769 x2 series even need a fuel gauge and/or
What is the suitable fuel gauge for…
Part Number: BQ76942 Dear TI experts,
We have used your company's BQ76942 chip in our product, and the application circuit diagram is shown in the following figure. Only one pair of charge and discharge MOSFETs are used in the circuit, with a VGSTH…
Hello Henning,
I really want to apologize for the long wait here.
I was testing things out on my board and found something interesting. I ran the example I shared earlier (From the other E2E) and it actually worked just fine on my I2C CRC-enabled device…
Part Number: BQ76942
As shown in the (simplified) drawing attached, this design needs to detect a disconnected battery cable specifically in the place shown , and report this to the MCU (ideally by driving the Alert pin). This needs to be reported to the…
Part Number: BQ76942 Hi,
After OTP is done to BQ76942, can you still configure I2C Hex Addresses or should it be determined ahead of time?
Thank You,

Part Number: BQ76942 Other Parts Discussed in Thread: BQSTUDIO , EV2400 I am having trouble writing the OTP memory on a custom board using the EVM. I jumper over the CLK, SDA, and ground. I can communicate fine until I "Write All" to the target. Then I…
Part Number: BQ76952 Other Parts Discussed in Thread: BQ76942 HI
I am planning to use Bq76952 and Bq76942 in stacked configuration.
I would like to know how to achieve synchronization between Bq76952 and Bq76942.
Can the MCU read the data from both the…
