When TPS25830 is powered on, are there any timing requirements for EN, VBUS, ctrl1 and ctrl2?
At present, it is found that when the external computer uses the adb function, ctrl1 and ctrl2 are pulled high first, and VBUS will supply power in the reverse direction. Then control EN or Ctrl1 and ctrl2 of 25830, and find that the computer cannot recognize 25830. How can I restore the chip in this scenario?
Even after re-unplugging and re-plugging the wiring harness, the computer can no longer recognize it after discharging it. Please help me find out what state the chip is in at this time. How to solve it?
