Tel：886-3-5645656 Fax：886-3-5645626 VM149D 120mA, 10-Bit Current Sinking VCM Driver with I2C Interface General Specifications The VM149D 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 2.3V to 3.6V. 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 VM149D is designed for applications such as image stabilization, autofocus in camera phones, and other portable devices.
