Auto sensor control

There are many electronic sensor modules in automotive. These sensors connect to the auto body bus in order to monitor and manage the sensors running status and report to the major body controller. The auto sensor control module is based on MindMotion MM32F0140 product series. Below system shows the examples using MM32F0144C6P or MM32F0144C6PV (working temperature can be up to 105C) as the main controller.

- Implement the real-time monitor to the sensors’ current, voltage, temperature, etc, via high sampling rate ADC interface
- Implement the communication with auto body system, via high performance FlexCAN bus
- Featured with 2.0-5.5V broad voltage power supply, high reliability, and 105C working temperature
