PRODUCTS

Actuator Driver

Actuator driver ICs provide vibration 
feedback, providing intuitive and 
effective feedback to the driver 
when interacting with the vehicle


Tech Overview

01

Supports precise control of vibration, movement and acoustic signals of LRA, VCM and Piezo actuators


Key Features 

02

High-sensitivity tactile support with vibration intensity and precise vibration control 

Automatically tracks the actuator's resonant frequency for optimal operation

Fast, accurate, and reliable response while reducing power consumption

Built-in safety features, including overcurrent and overheat protection, ensure reliability

Compact, lightweight package for limited vehicle space

Supports communication and control interfaces optimized for vehicle environments


Applications

03

Automotive Touch Buttons, CCP Button, Central Display, Passenger Display, E-Shift, CID (Central Infotainment Display)
