✅ Ultimate Integration, Easier DesignThe ACM6731 is a highly integrated three-phase BLDC motor driver chip, integrating the following functions internally:
What does this mean? No external current sense resistor is required, and no complicated drive circuit design is needed. A single chip completes all functions from control to driving. Packaged in SOP8 with only 6mm×4.9mm dimension, it delivers an ideal solution for high power density applications.
✅ 180° Sinusoidal Drive, New Benchmark for Low NoiseHigh-order harmonics generated by traditional square-wave drive usually cause annoying electromagnetic noise. The ACM6731 supports 180° sinusoidal drive, effectively eliminating electromagnetic acoustic interference caused by high-order harmonics and enabling quieter and smoother motor operation.
Meanwhile, for scenarios requiring fast startup and high torque output, the ACM6731 also supports square-wave drive mode. One chip for dual modes with flexible switching.
✅ Wide Voltage Range, Broader ApplicationsInput Voltage: 2.7V - 16V (Absolute Maximum Rating: 30V)Peak Phase Current: 2.4AOn-resistance: 300mΩ (High-side + Low-side)
From low-voltage portable devices to industrial applications, the ACM6731 handles all scenarios with ease.
✅ Three Speed Control Modes, Flexible CompatibilityThe ACM6731 offers three flexible speed control methods to meet diverse application requirements:
Analog Voltage Speed Control: 0–4.5V linear speed regulation, simple and intuitive
PWM Duty Cycle Speed Control: Supports 25kHz / 50kHz / 100kHz frequency
Clock Frequency Speed Control: Rotation speed controlled by input frequency
No matter which control method your system adopts, the ACM6731 achieves seamless compatibility.
✅ Full-range Protection, Safe and ReliableThe ACM6731 is built with multiple protection mechanisms to safeguard both the chip and the motor.
