The CN3969P is a single 10-bit DAC with 120mA output current sinking capability and has an 10KByte EEPROM Memory. Designed for linear control of voice coil motors, the CN3969P is capable of operating voltage from 2.3V to 3.6V. The SAC (Smart Actuator Control) mode is applied to minimize mechanical vibrations automatically. The SAC mode highly improves the actuator’s settling time and tolerance coverage compared with conventional LSC (Linear Slope Control) mode. Both DAC and EEPROM are controlled via a I2C serial interface that operates by clock rates up to 1MHz. The CN3969P incorporates with a UVLO reset circuit, power-down function, and exactly matched sense resistor. UVLO reset circuit ensure when supply power up, DAC output is to 0V until valid write-bit value takes place. It has a power down features thatreduces the current consumption of the device to 1uA maximum. The CN3969P is designed for auto focus and optical zoom camera phones, digital still cameras, and camcorders applications. The I2C address for Driver IC is 0x18/0x1C when ID pin is high/low respectively, while the I2C address for EEPROM is 0xB0/0xA0 when ID pin is high/low respectively.
