Haptics & piezo drivers
Drive tactile, acoustic and precision motion systems with reliable haptic and piezo driver solutions
Browse by category
Our haptics and piezo driver portfolio enables precise control of vibration, movement and acoustic signals across a wide range of applications— from smartphones and wearables to industrial systems and medical devices. Whether you're driving linear resonant actuators (LRAs), eccentric rotating mass (ERM) motors, piezo buzzers, or ultrasonic transducers, our drivers offer fast response times, low power consumption and compact integration. With support for analog, PWM and I²C inputs, advanced waveform control, and built-in diagnostics, TI helps simplify mechanical design and enhance system performance.
What makes our haptics & piezo drivers different?
Enhanced haptic performance
Our haptic drivers deliver precise, low-latency tactile feedback optimized for LRA, ERM, and solenoid actuators, with auto-resonance tracking and always-on haptics (AoH).
High-voltage piezo drive
Drive piezo actuators efficiently with integrated boost converters, eliminating external components and simplifying designs for a low BOM cost.
Contactless, reliable lens cleaning
Controlled ultrasonic vibration removes water, ice, dust, and contaminants from camera and sensor lenses without wipers or manual intervention.
Built-in sensing and diagnostics
Integrated resonance tracking and fault detection enable accurate actuator operation and real-time visibility into system health.
