I did a welding test and found that it was inconsistent with the datashit (yes). In order to avoid chance and make the experiment accurate and universal, I changed 3 ICs and found that the output voltages were exactly the same (accurate to the hundredth), as shown in the picture: QQ picture 20200420062707.jpg QQ picture 20200420062740.jpg QQ picture 20200420062711.jpg And this is the voltage value given by datashit:

	AB short circuit	BC short circuit	No short circuit
DM to ground voltage	2V	2.7V	2.7V
DP to ground voltage	2.7V	2V	2.7V

Plan to test again after replacing PCB

After replacing the PCB, I found that the voltage was almost the same
