Hi all.
Hope you can help with an issue.
Designed a circuit following the design example. MID boost while using a thin 1m cable that runs near motors.
When the board was connected to PC (no slave device) it shows up as failed to enumerate USB device in windows device manager.
It was drawing 200mA and the chip got hot. Did not detect any short to ground and measured 0.5V at Vreg output.(should be 1.8V)
Replaced chip, worked for some time (1.8V at vreg) and then developed the same issue again.
My only guess was an ESD event, but would that cause the chip to overheat?
Any advice?
Tks
