Automotive Cockpit System with Haptics

Overview

This advanced cockpit system features the next-generation haptic human machine interface (HMI).

System Benefits:

  • Low-latency direct drive for haptics drives distinct haptic effects triggered by multiple inputs without having to wake the apps processor.
  • BroadLED™ backlight driver technology in the LED driver provides best-in-class LED current matching with the highest possible efficiency.
  • A flexible system power management IC (PMIC) can supply a wide range of multicore system-on-chip ICs (SoCs) and integrates full power rail management with multiple sleep modes for an optimized system.
  • Reduces cost and development time using PMICs verified for R-Car SoCs.
  • Reference boards provide a quick and easy start to development.
