A89301 - 50V Ultra Low Noise FOC Motor Controller

Datasheet Summary

Description

The A89301 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).
  • I2C interface for speed control and status readback.
  • Ultra-quiet low speed operation.
  • Proprietary non-reverse fast startup.
  • Soft-On Soft-Off (SOSO) for quiet operation.
  • Analog / PWM / Clock mode speed control.
  • Closed-loop speed control.
  • Configurable current limit.
  • Windmill startup operation.
  • Lock detection.
  • Short-circuit protection (OCP).
