My name is Maria Agalidis and I'm from Renesas Electronics. Today we’re going to talk about sensor signal conditioning.
The main challenge in the automotive world for sensors is to capture an analog signal and to convert it reliably into digital information for a microcontroller in the car.
Our SSCs (Sensor Signal Conditioning Devices) today are capturing pressure and temperature and convert it into precise information in the car. Despite the challenging environment like EMI, voltage drop, noise, our products are able to deliver accurately data.
Our demo is a clear example of sensor signal conditioning operating in a harsh environment like exhaust gas system. In this demo we can see two high temp probes and two pressure sensors that are controlling and monitoring the particle filter. The sensors are measuring the efficiency of the exhaust system and they are also sending diagnostics to the control unit. The ICs are dual channel solution and can serve two sensing probes.
This makes it a very cost efficient and flexible solution. That's why today all Tier1s are using SSC in different sections of the car.
