LP8864S-Q1: LP8864 Boost output

Hi,

Our expert will check and update you soon,

 Hi, Haitao

As the boost output is 43V, so the controller is worked. May I kindly know if any fault is triggered when you connect to the panel? and any kind of failure is reported?

Hello Zhiqian

Thank you for your reply. It's possible that a fault was triggered during the test because an arc occurred during the test OUT process. But can't it recover by itself after being powered on again? After we debugged later, we found that the chip was indeed not damaged, but the MCU needed to re-burn the program before it could return to normal. Could you please help explain this? Thank you
