描述 Description

Ultra Slim, High Performance VCM Driver

DW9719T is with small package size and single 10-bit DAC with 100mA output current sinking capability, which is designed for linear control of voice coil motors(VCM), capable of operating voltage up to 4.8V Smart Actuator Control(SAC) mode is applied to minimize mechanical vibrations automatically. SAC mode highly improves the actuator’s settling time and tolerance coverage compared with conventional Linear Slope Controlmode(LSC). DW9719T is controlled via I2C serial interface, which is supported Fast Mode Plus.
DW9719T has a Power On Reset(POR) circuit and power down mode. POR circuit gets to operate when supply power turns on. The output current keeps 0mA until valid register value takes place. During the Power Pown(PD) mode, it consumes max. 1uA.
DW9719T is designed for auto focus applications in mobile cameras, digital cameras, and other nano actuator applications.
