Part Number: LP8866-Q1 Hi Team
請幫忙釐清下方問題THX
LP8866系列一上電後,如果出現當機現象,無法單存靠I2C指令進行回復,只能透過斷電重啟
LP8866系列,若不進行斷電,則需斷開低壓3.3V端的電,重新上電才能夠重置
但如果斷開LP8866的低壓端的電源,但其他IO並未進行斷電,如fault/EN/I2C/或有pull Hi的端點有持續供電3.3V,則此種斷電是無效,因為會產生電壓回灌現象
就認知 Fault腳 應該是開集極的架構,狀態是屬於隔離的,…

Part Number: LP8866S-Q1 Hi Team,
I am using direct PWM mode for LP8866SQDCPRQ1. Resistor 7.87K connected with MODE pin to GND.
I hope, it means then LED out frequency will be same as input PWM frequency.
In that case, is there any relevance to add PWM…
