The CM401 consists of a built-in MCU, flash memory, SRAM and proprietary power delivery, position sensing and precision control logic, especially tailored for SMA actuators.

The chip can drive SMA-based lens shift OIS actuators and is only the first in a family of high-performance driver ICs for precise control of camera actuators and other SMA-based applications such as 3D sensing, haptics and many more.

The first shipment of CM401 chips has been made for a premium smartphone handset launching soon. Further announcements of CML’s driver IC launches will be made over the forthcoming months.
