MP6539 as BLDC FOC gate driver

Hi, all

I am discussing to use MP6539BGF-Z as gate driver for servo(FOC) control BLDC in-wheel motor.
with STM32F407VE as main MCU and IMC101T-F064 as logic controller.

I want to make PCB that controls motor for constant speed with high torque also zero speed with holding torque.

So my question is :

  1. should my idea works?
  2. as manual, CSO(current sense output) goes ~6V when over current detected. It could damage STM32(3.3V system)? -> should I step down CSO?
  3. any other products or solutions for my desire?
