MP6632 - Three-Phase BLDC Motor Driver

General Description

The MP6632 is a three-phase brushless DC (BLDC) motor driver controller with up to 1A of driving current.

It drives three-phase BLDC motors, with a 6V to 50V input voltage (VIN) range.

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 MP6632 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 protections include under-voltage lockout (UVLO), locked-rotor protection, o.

DESCRIPTION The MP6632 is a three-phase brushless DC (BLDC) motor driver controller with up to 1A of driving current. It drives three-phase BLDC motors, with a 6V to 50V input voltage (VIN) range. The MP6632 controls the motor speed through the pulse-width modulation (PWM) signal or the DC signal on the PWM/DC pin with closedloop/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 MP6632 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.
