Part Number: BQ76942 Other Parts Discussed in Thread: BQSTUDIO Tool/software: How to Configure BQ76942 for Standalone Operation.
Is BQSTUDIO Required for Standalone Configuration?. If so can I directly connect BQSTUDIO to bq76942 without MCU.
Part Number: BQ76942 Tool/software: Hi TI experts,
I set the speed of IIC communication between bq76942 and MCU to 400K, but when I tested the IIC waveform, I found that the delay of tSU:STA and tSU:STO did not meet the minimum 600ns requirement of the…
Part Number: BQ76942 Tool/software: Dear TI experts,
Assuming that in the battery management system, after pressing the power button, the MCU activates the AFE BQ76942 and completes initialization, and then the communication between the MCU and AFE…
Hello GJ H, Thank you for your patience and for sharing your labeled waveforms. From the looks of it, you most likely entered the Soft SHUTDOWN state for the device. More information regarding how Soft SHUTDOWN is entered and how to avoid/exit it, can…
Part Number: BQ76942 Tool/software: HI Ti Experts，
When I tested the bq76942 to enter shutdown mode, I found the same conditions, but sometimes it failed to enter. My logic for entering shutdown mode is that the software sends a shutdown command and…
Part Number: BQ76942 Tool/software: Hello TI Team, I've just encounted a problem that i didn't find a solution. I am designing a 7-cell BMS board. But i am just wondering: Will the BQ76942 help me charge these batteries correctly and safely if…
Part Number: BQ76942 Tool/software: Hi, TI team.
I have a question about bq76942.
In my case the battery consists of 4 removable 18650 lithium cells . The user may accidentally insert one or more of the cells in reverse polarity.
I have reviewed the VC0…
Part Number: BQ76942 Tool/software: I am working on an Arduino based data logger as I2C interface with BQ76942.
I have written a basic code to check out the cell voltages. But the problem is, I am getting the correct voltages every 6-7 readings. Am…
Part Number: BQ76942 Tool/software: Hi TI team,
I am currently working on the calibration of the BQ76942 chip. However, I have encountered an issue when attempting to read the raw ADC measurements. Specifically, when I try to access the 16-bit counts…
