3.2.3.2 MCT8316ZTEVM Quick Start Guide

The MCT8316ZTEVM requires a power supply source, which has a recommended operating range from a 4.5 V to 35 V. To setup and power the EVM, use the following the sequence:

  1. Connect motor phases to A, B, and C on connector J13.
  2. Connect Hall sensors to J11 and use HALL_PWR_SEL jumper J11 to select the supply as 3.3 V from buck or use an external supply on connected to J12. Ensure the MODE resistors are set correctly to use the appropriate Hall sensor configuration as described in MCT8316Z datasheet.
    1. If using the boards pullup resistors, populate J8–J10 with shunt jumpers to enable pullups. Connect the single-ended inputs to only the HPx pins on connector J11. This is the default of the MCT8316ZTEVM.
  3. Ensure resistors are populated in H/W variant resistors for desired hardware settings.
  4. DO NOT TURN ON the power supply yet. Connect the motor supply to VBAT or VM and PGND on connector J7.
    1. To enable reverse polarity protection and Pi filter, connect to VBAT.
    2. To disable reverse-polarity protection and the Pi filter, connect to VM.
  5. Select J3 to 5V_USB and J5 to 3V3COM to power MSP430 from USB power supply.
  6. Connect the micro-USB cable to the computer.
  7. Turn the potentiometer fully clockwise to set the motor to zero speed upon power up.
  8. Turn on the motor power supply.
  9. Use the potentiometer to control the speed of the motor and the switches to disable the motor driver, change the direction, or apply a brake to the motor. Optionally, use the GUI (as shown in the MCT8316ZTEVM User's Guide) to monitor real-time speed of the motor, put the MCT8316ZT into a low-power sleep mode, and read status of the LEDs.
