AMT49400 Datasheet Integrated Sensorless Foc Bldc Driver

Manufacturer: Allegro MicroSystems

Overview: AMT49400 Integrated Sensorless FOC BLDC Driver.

General Description

The AMT49400 is an advanced 3-phase, sensorless, brushless DC (BLDC) motor driver with integrated power MOSFETs.

A minimal application circuit can be achieved with only two external components due to device’s high level of integration, which includes control algorithm, analog circuit, and power stage.

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

Key Features

  • Coding-free sensorless field-oriented control (FOC).
  • Standby mode current less than 10 µA.
  • Quiet and quick startup.
  • Only two external components for minimal.
