A89307 - Automotive FOC BLDC Motor Controller

General Description

The A89307 is a 3-phase, sensorless, brushless DC (BLDC) motor driver (gate driver) that 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.

Key Features

  • Code-free sensorless field-oriented control (FOC).
  • Constant speed, constant torque, constant power, and open-loop operating modes.
  • I2C interface for speed control and status readback.
  • Programmable, flexible in-to-output transformer.
  • 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.
