4. Align the base so that the wires of the sensor board and the wires of the motor are all facing the direction of
the opening on the motor enclosure. Return the screws that were removed in Step 1 and tighten. See Figure
3-7 .

3.2.2 Connecting TMAG5115EVM to a motor driver
The following connections must be made from TMAG5115EVM to a motor driver or motor controller in order to
commutate a motor:
1. Connect the black GND wire to GND or the V- connection to the power supply.
2. Connect the red VCC wire to VCC or the V+ connection to the power supply.
3. Connect the blue wire (Hall A) to the phase A connection.
4. Connect the green wire (Hall B) to the phase B connection.
5. Connect the white wire (Hall C) to the phase C connection.
6. No external pullup resistors are required with TMAG5115EVM because the necessary pullup resistors are
populated on the EVM board.
a. You can remove the pullup resistors on the TMAG5115EVM if your motor driver includes pullup resistors
for the Hall-effect sensor inputs.
3.2.3 Example Using MCT8316ZTEVM
Texas Instruments offers several motor drivers that can be used to spin BLDC motors. This section explains
what connections must be made to spin a motor using the MCT8316ZEVM:
3.2.3.1 MCT8316Z Overview
The MCT8316Z is an integrated three-phase gate driver IC with sensored trapezoidal control for motor drive
applications. The device provides three integrated half-bridges and a sensored trapezoidal algorithm capable of
directly driving a 3-phase brushless-DC motor. The algorithm is included in the IC, therefore there is no need to
create your own commutation algorithm to spin a BLDC motor. The MCT8316Z simply takes the inputs of the
Hall-effect sensors and uses them to drive the motor appropriately.
