Product Overview

The A4964 is a three-phase, sensorless, brushless DC (BLDC) motor controller for use with external N-channel power MOSFETs and is specifically designed for automotive applications. It is designed to provide the motor control functions in a system where a small microcontroller provides the communication interface to a central ECU and intelligent fault and status handling. The A4964 provides the supply and watchdog for the microcontroller and the high-voltage interfaces between the microcontroller and the central ECU and ignition switch. The A4964 can also operate as an independent singlechip remote motor controller.
  • Three-phase sensorless BLDC motor control FET driver
  • Three-phase sinusoidal drive with soft start
  • Sensorless start-up and commutation
  • Windmill detection and synchronization
  • Bootstrap gate drive for N-channel MOSFET bridge
  • Programmable control modes: speed, voltage, current
  • Peak current limiting
  • Control via SPI or PWM
  • Programmable gate drive for slew rate control
