描述 Description

High Efficiency Driver IC for VCM

DW9718S is designed for linear control of voice coil motors(VCM). DW9718S is a single 10-bit DAC with 100mA output current sinking capability. As well as in lineal mode the part can operate in switched mode, increasing the power efficiency of a typical voice coil auto focus system. This device features Smart Actuator Control (SAC) mode which can minimize the mechanical vibration and achieves faster mechanical settling time.
DW9718S operates from a single 2.3V to 4.8V supply. The internal DAC is controlled via I2C serial interface that operates at clock rate up to 1MHz. DW9718S offers a Power Down(PD) mode with current consumption less than 1uA.
DW9718S can be used for auto focus applications in mobile cameras, digital cameras, web cameras and action cameras.
