Hi Pavlin,

There are a few more items to check.

Please check and report the voltages on V5, VINT, and VCP before and after the previously described steps.

Also, if you have a pullup on the FAULTn pin, please report its voltage.

After the described steps, it is expected to find

V5 = ~5V

VINT = ~1.8V

VCP = ~VM + 10V

FAULTn = ~pullup voltage (logic high)

Would you please repost the schematic by selecting "Use rich formatting" to the bottom right of the reply window. Once selected, click the "Insert File" icon and add the schematic. The link is not viewable due to site restrictions.
