General Description

The MPQ6631H is a three-phase, brushless DC (BLDC) motor driver with integrated power MOSFETs.

The device supports a single external Hall sensor or three external Hall-effect sensors to drive a three-phase BLDC motor, with up to 3A of peak phase current and an input voltage (VIN) range between 3.6V and 35V.

The MPQ6631H controls the motor speed through the pulse-width modulation (PWM) signal or the DC signal on the PWM/DC pin with closed-/open-loop control.

Key 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 MPQ6631H 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. Rich protection features include input overvoltage protection (OVP), under-volt.
