The EV6631-L-00A is an evaluation board designed for the MP6631, a three-phase brushless DC (BLDC) motor driver with integrated power MOSFETs. The MP6631 drives a three-phase BLDC motor with a single external Hall-effect sensor or three external Hall-effect sensors. The peak phase current is up to 3A across the 3.6V to 24V input voltage (VIN) range.
The MP6631 controls the motor speed via the pulse-width modulation (PWM) signal or the DC signal on the PWM/DC pin with closed-/open-loop speed control. The device features 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 MP6631 provides rotational speed detection. The rotational speed detector (the FG/RD pin) is an open-drain output. It outputs a high or low voltage relative to the Hall comparator’s output. Direction control is achieved via the DIR pin’s input.
Full protection features include under-voltage lockout (UVLO) protection, locked-rotor protection, over-current protection (OCP), and thermal shutdown.
The MP6631 is available in a QFN-26 (3mmx4mm) package.
