EUM6820 100mA Current Sink VCM Driver with I2C Interface DESCRIPTION The EUM6820 is a single 10-bit DAC with 100mA output current sink capability. It features an internal reference, I2C interface, 10 bits DAC and current sense resistor. The DAC is controlled via a 2-wire (I2C compatible) serial interface that operates at clock rates up to 400kHz. The EUM6820 can operates from 2.3V to 5.5V. The EUM6820 incorporates a power-on reset circuit, which ensures that DAC output powers up to 0V and remains there until a valid write takes place. It has a power-down feature that reduces the current consumption of the device to 1µA maximum. The EUM6820 principally designed for linear control of voice coil motors, targeting at autofocus, image stabilization, and optical zoom applications in camera phones , digital still cameras, and camcorders. While it may also used in many industrial applications, such as controlling temperature, light, and movement. The I2C address for the EUM6820 is 0 × 18. FEATURES 100mA current sink 2-wire (I2C-compatible) 1.8V serial interface 10-bit resolution DAC 2.3V to 5.5V power supply Guaranteed monotonic over all codes Power-down to 0.5µA typical Internal reference Current sense resistor integrated Power-down function Power-on reset Available in 1.0mm × 1.5mm WCSP-6 package RoHS compliant and 100% lead (Pb)-free APPLICATIONS Camera phones Digital still cameras Web/PC cameras Digital video cameras/camcorders Lens autofocus Lens covers Optical zoom Image stabilization Shutters Neutral density filters Application Circuit Figure 1.
