EVQ6631H-L-00A

The EVQ6631H-L-00A is an evaluation board designed to demonstrate the capabilities of the MPQ6631H-AEC1, a 3-phase brushless DC (BLDC) motor driver with integrated power MOSFETs. The MPQ6631H-AEC1 drives a 3-phase BLDC motor with one external Hall sensor or three external Hall sensors. The peak phase current reaches up to 3A across the 3.6V to 35V input voltage (V_IN) range.

The MPQ6631H-AEC1 controls the motor speed through the pulse-width modulation (PWM) signal, or it controls the DC signal on the PWM/DC pin. The device provides closed-/open-loop control and a built-in, configurable speed curve function. The device also features a sinusoidal drive for maximum torque, as well as low speed ripple and noise across the full speed range.

The MPQ6631H-AEC1 has a rotational speed detector feature. The rotational speed detector (the 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.

Protections include input over-voltage protection (OVP), under-voltage lockout (UVLO), locked-rotor protection, over-current protection (OCP), and thermal shutdown.

The MPQ6631H-AEC1 is available in a TQFN-26 (3mmx4mm) package with wettable flanks. It is available in AEC-Q100 Grade 1.
