The VM147 is a VCM(Voice Coil Motor) driver IC with I2C interface control that is capable of programmable sinking output current. It has a built-in internal voltage reference and operates with a supply voltage range from 2.4V to 5.5V. The DAC is controlled by a signal transmit through a 2-wire I2C serial interface which operates in an I2C fast mode (400 kHz). The VM147 is designed for applications such as image stabilization, auto-focus, optical zoom in camera phones, and other portable module devices.
