110mA, 10-Bit Current Sinking VCM Driver

with I

2C Interface

General Specifications

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.
