Dear TI experts~
There are 2 problems about DRV8850
1. When we tested in the lab, the chip performed normally; after the prototype was handed over to the customer, there was no output of the chip, and it returned to normal after replacing the chip.
2. During the previous test, the entire circuit was short-circuited; the current was too large after power-on, and the LDO did not work.
If you can leave a email，I can send you the Schematic~
