IC solutions for LED ambient light, BLDC, Stepper and DC motors, USPA and gesture control

Elmos will show high-performance IC solutions for automotive LED ambient at the electronica India (September 25–27, 2019). Furthermore Elmos shows highly integrated, programmable motor controller for controlling BLDC, Stepper and DC motors and other high-end solutions for automotive trends. The electronica India takes place at Greater Noida, Delhi NCR – you will find the Elmos solutions at the booth of our distributors Swingtel (ED11 Hall 10) or Millennium (ED01 Hall 10).

The Elmos IC E521.36 enables a variable, cost-efficient and very space-saving design of RGB LED modules for the connection to a LIN bus. Possible application is the ambient lighting in the vehicle interior. The device includes a powerful 16-bit microcontroller with 32 kbyte NVM, 128-byte EEPROM and a LIN transceiver that meets the requirements up to LIN 2.2. The integrated microcontroller can be programmed with IAR's widely used software development environment. The addressing in the network takes place with the integrated BSM auto-addressing (bus shunt method). Furthermore, the device has three current sources, each with up to 40mA and three 16-bit PWM generators. The 48MHz PWM clock ensures full 16-bit color resolution at a 732Hz repetition rate, enabling flicker-free applications and meeting all known OEM requirements.

Motor Control
With the E523.42, Elmos presents a highly integrated motor controller, enabling its customers to realize a powerful and cost-effective implementation of motor control for 12V automotive applications. The IC combines a 32-bit ARM® Cortex® M0 microcontroller and an analog motor driver in a small QFN5*5 package. The three integrated half bridges allow the direct control of motors with 600mA each (RMS) and in boost mode even with up to 1A phase current. The IC can drive either a three-phase BLDC motor, a three-phase Stepper motor, or up to two conventional DC motors. Possible applications include: actively controlled louvers, water valves or small and medium fans, for example in car seats.

Ultrasonic Parking Assistance (USPA)
With the ICs E524.08 and E524.09 Elmos presents another ultrasonic IC family for the ultrasonic parking assistance systems in the vehicle. Furthermore, these ICs can be used for general distance measurements in industrial applications (industrial robots, silo level detection, etc.). During the development of these ICs special focus was placed on an optimal range detection. Thus, the revised signal path currently allows distance measurements between 10cm to 600cm. With optimized system hardware and good environmental conditions, even longer distances are possible.

Gesture Control
The Elmos HALIOS® ICs E909.21 (controller) and E909.22 (conditioner) enable optical proximity and gesture recognition in the vehicle. The controller and conditioner are designed for use in larger automotive displays. The combination gives the user a perfectly coordinated solution for precise interaction with the graphic user interface (GUI). The following actions can be detected: Proximity, Swipe, Air Slider ™, Magnification, and more. The object recognition and motion evaluation act in real time on the basis of a simple infrared technology. Elmos is a pioneer in gesture recognition in the vehicle and the No. 1 in the world for this application. The E909.21 is used by well-known OEMs in various vehicle models in series.
