4.1 Hardware Connections Overview – MCT8316AEVM
Figure 4-1 shows the major blocks of MCT8316AEVM evaluation module. The MCT8316AEVM is designed
for an input supply from 4.5-V to 35-V. The MCT8316A includes three integrated half-bridges and implements
a sensorless trapezoidal control algorithm to spin a motor with up to 8-A peak current. It also integrates an
adjustable buck regulator.

4.2 Connection Details
Figure 4-2 shows the connections made to the MCT8316AEVM in order to spin a 3-phase sensorless Brushless-
DC motor.
An 4.5-V to 35-V power supply or battery is connected to the VBAT or VM and PGND terminals on connector
J7. There is a reverse polarity protection and Pi filter implemented on the VBAT and PGND terminals. To bypass
the reverse polarity protection and Pi filter, connect the power supply to the VM terminal or VM test point on the
board and PGND.
The three phases of the BLDC motor connect directly to the A, B, and C terminals of the screw terminal
connector J8 provided on the MCT8316AEVM.
