General Description

The A89306 is a 3-phase sensorless brushless DC (BLDC) motor driver (gate driver) which can operate from 5.5 to 50 V.

A field-oriented control (FOC) algorithm is fully integrated to achieve the best efficiency and acoustic noise performance.

Constant torque and constant power modes are provided, as well as constant speed and open-loop operating modes.

Overview

A89306 50 V Ultra-Low Noise FOC Motor Controller.

Key Features

  • Code-free sensorless field-oriented control (FOC), for driving motors at up to 400 Hz.
  • Constant speed, constant torque, constant power, or openloop operating mode.
  • I2C interface for motor control and status readback.
  • Universal 32-point speed/power/torque/duty curve.
  • Ultra-quiet operation.
  • Proprietary non-reverse fast startup.
  • Soft-On Soft-Off (SOSO) for quiet operation.
  • Analog / PWM / Clock mode speed control.
  • Conf.
