Hi team,
Here's an issue from the customer may need your help:
The BQ76952 is controlled via IIC using the CH341 module. When using IIC, set the frequency 20K, BAT voltage 38V, and the logic analyzer grabs the IIC waveform as shown in the following figure, where SCL is pulled down for a period of time by randomly resulting in the signal cannot transmit properly. And the customer has modified to pull up resistor to connect an external 3.3V pullup supply. But the problem persists.
When don't connect to AFE, the waveform is as follows:
Could you help check this case? Thanks.
Best Regards,
Cherry
