New Smart Sensor from Micronas Simplifies LIN bus-based Automotive Applications
Micronas has announced the first member of the HAL 28xy sensor family, the HAL 2810. It is a Hall-effect sensor to include a programmable microcontroller and a LIN bus 2.0 interface.
The device is a smart sensor, integrating the sensing element, all necessary compensation functions, digital signal processing as well as full LIN bus connectivity. This reduces system cost and increases reliability, a key feature in networking automotive systems.
Micronas’ new family of sensors is ideal to replace potentiometers in automotive applications. The sensors can be used for angular measurements such as in fuel-level sensing and for linear movement such as in seat-track position. In particular, the HAL 2810 is well-suited for passenger weight detection.
US Federal Motor Vehicle Safety Standard 208 requires passenger airbags that can sense the size and weight of front seat passengers and adjust accordingly. The HAL 2810 measures the force on the seat attachment points and determines passenger weight based on these measurements.
