Micro-actuator Driver
General Specifications
11-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 voice coil motor, piezo-actuator, or other dc motor actuators. It is
suitable for camera module application or other portable device.

Application Notes
…
…
The O1/O2 output H/H or L/L will brake the motor. 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.
