HVLED001A - FB pull-up current suddenly increases from cca 0.6mA to 1mA.

Hi all, I am confused about FB pull-up current. At start, ZCD detects overvoltage, so I understand that FB is pulled down. After 300ms, FB is pulled by 0.6mA and after next 500ms FB is suddenly pulled by 1mA. How does overvoltage protection work? How...

Partial charge with STBC15 ?

I can not do the partial charge with STBC15. For example, when the battery is in the BSP state (system is powered by the battery) and the Vbat is 3.8V, if I plug the charger then unplug the charger after some seconds, the Vout is off (0V) ! This is ...

Cooling of L6201PS Motor Driver

I want to use the L6201PS Motor Driver for a motor (24-48V) and the max. current is 4A. My Question is at which current value do I need a coolant? I found out in the datasheet that I only need some ground area for cooling, is that correct?
