4 Hardware and Software Overview
4.1 Hardware Connections Overview – MCT8316ZTEVM
shows the major blocks of the MCT8316ZTEVM evaluation module. The MCT8316ZTEVM is
designed for an input supply VBAT from 4.5 V to 36 V. The MCT8316Z includes three integrated half-bridges and
implements a sensored trapezoidal algorithm to spin a motor with up to 8-A peak current. It also integrates an
adjustable buck regulator and can support many types of Hall sensor configurations or be used to power external
circuits.

4.2 Connection Details
shows the connections made to the MCT8316ZTEVM to spin a 3-phase sensored brushless-DC
motor.
A 4.5-V to 36-V power supply or battery is connected to the supply voltage (VBAT) or motor voltage (VM)
and PGND terminals on connector J7. There is a reverse-polarity protection and Pi filter implemented on the
VBAT and PGND terminals, resulting in a 0.7-V diode voltage supply drop to VM. To bypass the reverse-polarity
protection and Pi filter, connect the power supply directly 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 J13 provided on the MCT8316ZTEVM.
Use connector J11 on the MCT8316ZTEVM to connect single-ended digital or analog differential Hall inputs. Use
HALL_PWR for Hall power and AGND for Hall ground. If connecting analog inputs from a Hall element, connect
