DESCRIPTION
The MEZS6-45V15ABLDCDriver is a controller
and driver for a three-phase brushless motor.
It operates from a supply voltage of up to 45V.
It is configured to drive three half-bridges
consisting of six N-channel power MOSFETs.
The rotor position information is provided by the
Hall sensors assembled in the motor. Motor
speed and direction are controlled by an on-
board microcontroller.

QUICK START GUIDE
To quickly start using the MEZS6-45V15ABLDCDriver brushless DC (BLDC) motor driver board, follow
the steps below:
1. Connect the U, V, and W wires of a BLDC motor to the MOTOR connector on the board.
2. Connect the motor Hall sensors to the HALL connector on the board.
3. Connect a power supply (between 5V and 45V) to the VIN and GND pins.
4. Slide the DIR switch to “FWD” or “REV” to control the direction of the motor.
5. Slide the “RUN/STOP” switch to the right to run the motor.
6. Slide the “BRAKE” switch to the right to apply short braking to the motor.
7. Adjust the motor speed by turning the SPEED pot.
8. Pay careful attention to the correct input polarity connection to avoid damage due to a reversed
connection.
9. R25, R26, and R27 (each 200mΩ) limit the peak output current to about 7.5A because of the 0.5V
LSS OCP trigger threshold. Using a lower resistance value can provide a larger output current.
