Микросхемы и комплектующие A4964KJPTR-T

Контроллер/драйвер двигателя , 3-фазный DC бесщеточный, 5.5В до 50В, 9.5В/10мА/1 выход, LQFP-32

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

• 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
