Valve Driver Refresh - Coggle Diagram

- - - - FW based :question:
    - - Accuracy should be significantly improved over MC06XS4200
    - - Is there a way to do this with current feedback :question:
  - - - Peak Current vs Hold Current Characterization :question:
    - - Pressure Control
      - Current Control
        
        Copper has a 0.4% / C temperature coefficient of resistance.
        ~20% change in resistance over our typical on deck temperatures.
    - - PWM Resolution :question:
      - Greater or less than 20kHz (audible) :question:
    - - Magnitude :question:
      - Frequency :question:
        
        25-250Hz
  - - - Generally seems to be recommended
  - - - Daisy-Chainable?
- - - - Peak current vs hold current
    - - Look for hysteresis improvements?
- - - - Cost
      - Features
    - - Feature overload, more than we need.
      - Complexity
    - - Board real estate
    - - MC33PT2000
      - TLE82452
      - DRV110
      - DRV8106-Q1
  - - - Customized best for our application.
    - - Cost
      - EE/FW behavior development time.
      - Scalability.. Could be difficult to support applications that require large number of valves
    - - Board real estate
