Tel：886-3-5727171 Fax：886-3-5727390 MD311 MD311 Micro-actuator Driver General Specifications MD311 is a micro-actuator driver IC with miniature package. It is one channel low voltage bi-directional motor driver IC. The design is optimal for driving different type micro-actuator, such as OIS motors, voice coil motors, piezo-actuators, or other DC motor actuators. It is suitable for camera module application or other portable device. Features and Benefits ◆ Low voltage operation (VDD Min = 1.8 V) ◆ Low input current Zero standby current High frequency switch (1MHz) Thin, small package (LFCSP6 / WLCSP6) ◆ ◆ ◆ Pin Assignment Pin Num.

Though the active current of driver is near to zero, if the application is required to turn off driver, please turn off the driver’s power from VDD. The capacitor connected between the output nodes O1/O2 will reduce the noise generating by motor when the motor is switched to opposed direction.
