Automotive Body Electronics

Automotive body electronics applications are becoming increasingly complex as the demands on these systems extend to enable higher interaction between systems and the rest of the vehicle while adapting to space and energy consumption constraints. At the foundation of our body electronics portfolio is a family of AEC-Q100 qualified microcontrollers and wireless solutions. Silicon Labs’ products excel in body electronics applications such as anti-pinch window gate lifters for power windows, networked door controls, power seat controls, remote keyless entry and passive keyless entry, heating ventilation and A/C (HVAC) system for climate and comfort control, windshield wiper and rain systems, steering angle measurement and more.

Human Interface and Body Electronics

  • Silicon Labs offers the best capacitive touch sense solutions in the automotive market. The C8051F7xx/99x families have ultra low standby power for fast system wake-up and keyless functionality.
  • LCD displays are commonly used in electronic digital displays because of the extremely low electrical power and low voltage requirements. Silicon Labs’ CP240x can drive those LCD displays up to 128 segments for viewing in bright as well as dark conditions. USB interfaces are also available as bridge ICs for several serial bus standards (UART, I2C, etc..).
  • The Si114x infrared proximity and ambient light sensor family, using one to three infrared LEDs, powers functions such as back-lighting control and touchless motion/gesture recognition when driving.
