AMT49406 - 50V Code-Free FOC BLDC Motor Controller

General Description

The AMT49406 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.

Key Features

  • Code-free sensorless field-oriented control (FOC).
  • 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).
  • Brake and direction inputs.
