A89306 - 50V Ultra-Low Noise FOC Motor Controller

Datasheet Summary

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.

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.
