MP6631 - Three-Phase BLDC Motor Driver

Description

The MP6631 is a three-phase brushless DC (BLDC) motor driver with integrated power MOSFETs.

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. Rich protection features include under-voltage lockout (UVLO), locked-rotor prote.

DESCRIPTION The MP6631 is a three-phase brushless DC (BLDC) motor driver with integrated power MOSFETs. The device supports a single external Hall-effect sensor or triple 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 of 3.6V to 24V. The MP6631 controls the motor speed through 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.
