Cirrus Logic Introduces New Family of Advanced Closed-Loop Haptic Drivers for Next-Generation Automotive Interfaces

Automotive-qualified solutions for more intuitive, immersive in-vehicle experiences

Cirrus Logic (NASDAQ: CRUS), a leading provider of high-performance audio and mixed-signal semiconductor solutions, today announced the launch of its new family of closed-loop haptic drivers CS40L51, CS40L52 and CS40L53, marking the company’s first haptic driver solutions reliability qualified in accordance with the AEC-Q100 automotive standard. The new family of products brings Cirrus Logic’s proven expertise in consumer and smartphone haptics to the automotive space, enabling a more consistent, immersive and intuitive tactile user experience across a wide range of in-cabin interfaces.

As automakers look to elevate and differentiate vehicles with personalized, immersive experiences, haptics-enabled smart surfaces play a critical role in enabling premium interior designs that are sleek, modern and sustainable. Cirrus Logic’s closed-loop technology improves actuator response, creates a wider range of haptics effects and delivers consistent performance across varying conditions. This ensures high-definition haptic feedback on interactive displays, steering wheels, smart surfaces, center consoles, smart seats and more.

“Consumers expect a high level of responsiveness from haptics experiences. Early adoption of haptics in vehicles was not intuitive or consistently reliable, and didn’t deliver a realistic tactile experience,” said Vlad Bulavsky, Director, Automotive Solutions, Cirrus Logic. “Cirrus Logic’s new low latency, closed-loop haptics technology addresses this challenge for automotive designers who are redefining how we interact with our cars and take user experience to the next level.”

“As screens replace physical controls in vehicles, the industry has recognized the need for sophisticated tactile feedback to bridge the gap,” said Peter Cooney, Chief Technology Analyst at DATAportl, a leading market research provider. “We are moving past basic vibration to advanced, high-definition haptics that simulate physical textures and clicks. This shift is essential for reducing distraction and is the primary force driving the automotive haptics market today.”

Cirrus Logic’s CS40L51/52/53 family offers a range of features satisfying different use cases and budgets. It simplifies the design process for engineers by integrating key components into an efficient solution. The drivers’ advanced closed-loop hardware and algorithm improve the response time of the actuator and expand usable frequency bandwidth to create a wider range of haptic effects. These new haptics solutions support a broader range of tactile effects and enable new and better ways to leverage haptics for automotive user experiences.

CS40L51 – Combines advanced Sensor-less Velocity Control (SVC), real-time audio to haptics synchronization (A2H) and active vibration compensation (AVC) for immersive, high-fidelity feedback.

CS40L52 – Features the advanced closed-loop control SVC that optimizes the system's haptic performance in real-time by reducing response time, increasing frequency bandwidth and compensating for manufacturing tolerances and temperature variation.

CS40L53 – Features the Click Compensation algorithm to enable consistent haptic feedback across systems by adjusting haptic effects based on the actuator manufacturing characteristics.

By leveraging Cirrus Logic’s deep expertise in signal processing and consumer electronics, the CS40L51/52/53 drivers provide automotive designers with a scalable platform for both current and future generations of haptic-enabled automotive solutions.
