Actuator drivers

Improve actuator performance and reduce integration time with our actuator drivers

Our broad portfolio of actuator drivers with innovative algorithms and high integration reduce cost, board size, and power consumption while optimizing ERM, LRA, piezo and solenoid actuator performance in an array of haptics or touch-interface applications.

Haptic drivers

ERM & LRA drivers

Features such as auto-resonance detection and auto-overdrive/braking generate crisp haptic effects with LRA and ERM actuators.

Piezo drivers

High voltage piezo drivers with integrated boost converters simplify designs for any application.

Solenoid drivers

Solenoid haptic drivers with AEC Q-100 automotive qualification enable compelling, reliable vibration feedback anywhere in the car.

What it is: Haptic feedback or haptics refers to a type of user experience that is created via vibrations from an actuator. These vibrations can be used to simulate the feeling of touch on a capacitive screen or button, or vibrate an entire device for notifications. Haptics is commonly used in personal electronics such as smartphones or fitness trackers.

How it works: A touch event triggers the processor to fire a haptic event as a result. To achieve this, an analog or digital input signal is sent to the TI haptics driver. The TI driver then amplifies the signal or recalls a waveform from member and outputs to the actuator to create a vibration effect.

What else you need to know: our comprehensive ecosystem of haptics drivers, evaluation tools, and support resources simplify implementation and reduce time-to-market. Get started today with a few easy steps.

Solenoid drivers

Description LRAs can offer a richer user experience in a lower power solution compared to ERMs. ERMs are inertial motor-based haptic actuators with an off-center weight that rotates.
Piezo actuators can also be driven to high enough frequencies to produce audible noise. Solenoid actuators require high current and provide the strongest haptic responses.
