The EV6632-R-01A is an evaluation board designed to demonstrate the capabilities of the MP6632, a three-phase brushless DC (BLDC) motor driver controller with 1A of driving current. The MP6632 drives 3-phase BLDC motors, with a 6V to 50V input voltage (V_IN) range.

The MP6632 controls the motor speed through the pulse-width modulation (PWM) signal, or by controlling the DC signal on the PWM/DC pin. The device provides closed-/open-loop control and a built-in configurable speed curve function. It also features a sinusoidal drive for maximum torque, as well as low-speed ripple and noise across the full speed range.

The MP6632 also includes rotational speed detection. The rotational speed detector (FG/RD pin) is an open-drain output. FG/RD outputs a high or low voltage relative to the Hall sensor comparator’s output. In addition to rotational speed detection, the direction is controlled via the DIR pin’s input.

Rich protection features include under-voltage lockout (UVLO), locked-rotor protection, over-current protection (OCP), and thermal shutdown protection. 

The MP6632 is available in a QFN-32 (4mmx4mm) package.
