A4964KEVTR-J

The <bold>A4964</bold> 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 <bold>A4964 </bold>provides the supply and watchdog for the microcontroller and the high-voltage interfaces between the microcontroller and the central ECU and ignition switch. The <bold>A4964</bold> 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
