Current limiting by current chopping image

Need to complete DC bus sensing #2 scheme.

Way to perform current chopping. image

How to make a delay:

  1. Use 74VHC123AMX monostable
  2. Remove 74VHC123AMX monostable and use internal stm32 timer.

Monostable is not used. Signal from comparator goes to ETR pin on controller.
