My customer encountered a rare problem when using bq76940.
1. Bq76940 can work normally under normal working conditions;
2. When EMC testing is carried out in China, sometimes bq76940 will have a ready fault;
3. When conducting EMC test abroad, bq76940 often has xREADY fault, and can work normally after leaving EMC test environment;
In previous questions, some colleagues mentioned that the strong magnetic field environment may interfere with the power pin or TSN pin, resulting in an error.
Are there any documents or posts with such problems that you can share?
