Hi
The customer design with BQ51013B-Q1, Please refer to the following schematic and help check it.
1. PIN5 and PIN16 are short-circuited to ground, and the failure rate is about 0.1%.
2, Please help check whether there is any problem with the schematic design. They have tried connecting 10Ω resistors in series between pins 5 and 16, but the effect is not good.
3, In order to eliminate possible input high-voltage pulses, They tried parallel TVS, but the effect was not very good.
Waiting for your reply.
Thanks
