CXMD3207 is a sensorless 3-phase brushless DC motor driver IC. It senses the BEMF (Back electromotive force) of the motor in rotation and provides corresponding commutation current to the motor. The use of sensorless technology means no hall sensors are needed and makes the motor fabrication easy and especially for the small and thin DC motors since the IC is placed outside of the motor assembly

一.产品概述
CXMD3207 is a sensorless 3-phase brushless DC motor driver IC. It senses the BEMF (Back electromotive force) of the motor in rotation and provides corresponding commutation current to the motor. The use of sensorless technology means no hall sensors are needed and makes the motor fabrication easy and especially for the small and thin DC motors since the IC is placed outside of the motor assembly.
CXMD3207 series ICs have the functions of variable speed control, tachometer signal output, rotation direction control and shutdown mode, the motor including CXMD3207 IC can be controlled and detected by these features very easy from your system
二.产品特点
˙PWM (pulse width modulation) motor variable speed control
˙Built-in tachometer signal output (FG) for detection of motor speed
˙”Soft-switching” technique to reduce vibration and acoustic noise
˙Thermal shutdown protection
˙Rotor lock shutdown drivers protection and auto-restart function
˙Direction of rotation control (CXMD3207Ug only)
˙Shutdown mode with low standby current (CXMD3207Ug only)
