Introduction of three-phase 180˚ sine wave brushless DC motor driver IC-ACM6753

Product Overview

The ACM6753 is a three-phase sensorless motor driver IC with integrated power MOSFETs that can provide drive current up to 3.2 A peak. The ACM6753 is specifically designed for cost-sensitive, low noise, and low external component count applications.

The ACM6753 device uses a sensorless control scheme or single Hall control to provide a continuous sinusoidal drive IC, which greatly reduces the pure tone acoustics normally generated due to commutation. The algorithm configuration can be programmed through EFUSE, which allows the device to operate independently after configuration.

The ACM6753 receives speed commands via PWM input, analog voltage, or I²C commands. A large number of protection features are integrated into the ACM6753 to protect equipment, motors, and systems from fault events.
