DESCRIPTION

The EV6532-R-01A is an evaluation board for

the MP6532GR, a three-phase brushless DC

motor pre-driver.

The MP6532 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 (1)

To quick start the EV6532-R-01A, follow the steps below:

1. Connect the U, V, and W wires of a brushless DC motor to the motor connector. Connect the

motor’s Hall sensors to the Hall connector.

2. Connect a power supply (between 5V and 45V) to the VIN and GND pins.

3. Slide the DIR switch to “Fwd” or “Rev” to control the direction of the motor. Slide the “Run/Stop”

switch to the right to run the motor. Slide the “Brake” switch to the right to apply short braking to the

motor.

4. Adjust the motor speed by turning the speed potentiometer.

Note:

1) To avoid damage caused by a reversed connection, pay close attention to the correct input polarity connection.
