DW9714V Original DONGWOON 120mA Voice Coil Motor Auto Focus Driver IC with SAC™ Anti-Vibration Technology
DW9714V is a new generation linear VCM voice coil motor driver IC released by DONGWOON ANATECH, specially developed for camera module auto-focus systems. It shares fully identical pinout with DW9714A, supporting direct upgrade without PCB redesign. Integrated with high-precision 10-bit DAC, the chip delivers up to 120mA driving current to meet the thrust demand of long-range, high-load telephoto VCM actuators.
Adopting exclusive patented SAC™ intelligent vibration damping algorithm, it significantly reduces mechanical resonance at the start and end of focusing, shortens lens settling time and eliminates motion blur during photo shooting and video recording. It supports low-voltage startup at 2.3V up to 4.3V full battery voltage, perfectly matching portable devices powered by single-cell lithium batteries. The standard I2C serial bus supports maximum 1MHz high-speed communication, integrated POR power-on reset and ultra-low-power PD shutdown mode with standby current below 1μA to extend battery life of portable devices. Housed in ultra-miniature 6-bump WLCSP wafer-level package for compact camera module design.

FAQ Frequently Asked Technical & Sourcing Questions
Q1: Can DW9714V directly replace DW9714A without PCB modification?
A1: Both ICs share identical package and pin assignment, no PCB redesign required. Only register configuration to enable SAC™ vibration reduction function is needed on software side to achieve faster and more stable focusing performance.
Q2: What is SAC™ mode and what improvements can it bring to image quality?
A2: SAC™ is exclusive patented Smart Actuator Control technology of DONGWOON. It automatically suppresses VCM actuator resonance during focus startup & stop, shortens lens settling time, eliminates motion blur during snapshot and video recording, and improves image clarity under low light and fast moving shooting scenarios.
Q3: The chip supports 2.3V minimum operating voltage, can it be powered directly by single-cell lithium battery?
A3: Fully compatible. Single-cell Li-ion battery ranges from full charge 4.2V to discharge cut-off 2.3V with stable operation, ideal for battery-powered products such as action cameras and wireless cameras.
Q4: If host MCU only supports 400kHz I2C, can it drive DW9714V normally?
A4: The chip backward-compatible with standard 400kHz I2C fast mode. No hardware changes needed for legacy host controllers, communication speed will match automatically.
Q5: Can DW9714V with 120mA output drive long-travel telephoto VCM actuators?
A5: It provides higher current margin compared with regular 100mA driver ICs, suitable for high-load voice coil motors of 5MP~48MP main & telephoto cameras, delivering sufficient driving thrust and stable travel range.
Q6: How to request free samples, datasheets and register documents? Is stock available?
A6: GS-Micro maintains abundant genuine DONGWOON DW9714V inventory. Contact our sales team to apply for free samples, complete original datasheets, I2C register manuals and standard reference schematics.
