Future Changes

Due to tight time constraint, adding a hall effect current sensor will have to be in the next revision (2.0?)

Add Hall Effect Current Sensor

• Remove entire middle section with Hall Effect Current Sensor

  • Must connect to IN+ and IN-

    • Unsure if AND gate and MOSFETs need to be changed

• Links

  • Hall Effect Sensor for Current Sensing in High DC Voltage

• Part search

  • Check ratings (Current, voltage, sensitivity)

    • Current

    • Voltage

      • 120V?

    • Sensitivity [Check]

      • 0.806mV/A?

        • 3.3/2^12 (12bit ADC)
