The EVQ6632-U-00A is an evaluation board designed to demonstrate the capabilities of the MPQ6632-AEC1, a three-phase brushless DC (BLDC) motor driver controller with 1A of driving current. The MPQ6632 drives 3-phase BLDC motors, with a 6.5V to 50V input voltage (V_IN) range.  

The MPQ6632-AEC1 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 entire speed range.

The MPQ6632-AEC1 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 MPQ6632-AEC1 is available in a QFN-28 (5mmx5mm) package, and is available in AEC-Q100 Grade 1.
