Tool/software:
Hi team,
The customer found that TPS62869 work abnormally after SMT patch. They found that 1 pcs can't read the I2C address and no output. And another 1 pcs can read I2C address but also no output. So they want to know whether we can provide some judgment about which function in the devices works abnormally. They have tested Impedance of all of pin. And the abnormal devices PIN Impedance are the same as the normal PINs Impedance. If you have any suggestion about how to avoid such issue, please help share your comments.
