Business Area

In anticipation of the explosive increase in the number of devices equipped with AF functions, Zinitix has developed AF Driver IC and is currently continuously supplying it to major customers.

Open Loop Auto Focus Driver IC

Driver IC designed and developed by Zinitix to drive the actuator of the camera module using an autofocus function camera. It has a built-in driving IC EEPROM that determines the subject distance from the camera and automatically drives the lens in one or both directions to focus the image, allowing the user to store and use the desired data.


      

Core technology

- H-bridge voice coil motor(VCM) driver
- Embedded EEPROM Memory (10KByte or 16KByte)
- The 10bit DAC is controlled by I2C serial interface
- The DSC mode is applied to minimize the mechanical ringing.
- SLC(Soft Landing Control)
- AIPC(Auto Initial Position Control)

Closed Loop Auto Focus / OIS Driver IC

Driver IC designed and developed by Zinitix to drive the actuator of the camera module using an autofocus function camera. Closed Loop Driver IC is a driving IC that automatically drives the camera's lens by a built-in Hall sensor and provides more accurate focus through position correction. And OIS Driver IC is a driving IC that prevents focus shake caused by hand shake through position compensation by incorporating a Hall sensor.


      

    

Core technology

- Excellent reliability for shock with oscillation detection and prevention function
- Excellent noise characteristics with built-in IIR filter
- Linearity correction function
- Excellent temperature characteristics with built-in temperature sensor and compensation function
- Easy to manufacture multi-camera with I2C Auto Switching function
- Securing closed-loop stability with high-performance PID control algorithm
