Fax：886-3-5645626 Tel：886-3-5645656 VM114 VM114 Micro-actuator Driver with I2C Interface General Specifications VM114 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 devices. Features and Benefits ◆ Low voltage operation (VDD Min = 1.8 V) Low input current Zero standby current I2C serial interface ◆ Automatic power on reset ◆ Ultra small package: WLCSP (0.78*1.27*0.35mm) ◆ ◆ ◆ Ordering Information Part Number Package Marking VM114 WLCSP WLCSP, 6Pin TBD Micro-actuator Driver with I2C Interface Version：PRE.001 未經授權而逕予重製、複製、使用或公開本文件，行為人得被追究侵權之相關民刑事責任 Unauthorized reproduction, duplication, use or disclosure of this document will be deemed as infringement.

Page：3 VM114 Data Format VM114 Write Mode In the writing mode, data is written to VM114 and shifted into a 8-bit input register. After all 8 bits of data have been shifted in, a STOP signal is generated by master controller. The data in the input register is transferred to VM114 internal controller at the same time. VM114 Read Mode In reading mode, data is read from IC to a master controller in the same bit order.

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 generated by the motor when the motor is switched to opposed direction.
