Overview
NXP® and Tongji University jointly developed the anti-pinch window lift reference design featuring the MagniV® S12VR MCU, ideal for the development of power windows and sun roof systems.
- Includes hardware for real door/window in-vehicle applications, as well as software including anti-pinch algorithms and low-level S12VR drivers
- Aimed at reducing time to market, this design leverages unique features of the MagniV S12VR MCU
- Reduces unnecessary external components, lowers the total bill of material (BOM), improves system quality and saves space in automotive applications through a smaller PCB
Features
- Window manual/automatic up/down, automatic up/down with stop function
- Anti-pinch in both manual/automatic mode, anti-pinch region and force can be adjusted
- Stuck detection out of anti-pinch region, motor overload protection
- Soft stop when window is close to the top/bottom
- Fault diagnosis, indicating low voltage, over voltage/current/temperature etc.
- Low power mode (leveraging S12VR low power mode) to reduce power consumption
- Self learning, calibration by updating the window/motor parameters stored in EEPROM
- Use hall sensor as well as current sense to judge anti-pinch in algorithm
- Easy-to-control Graphics User Interface (GUI), set the parameters and get the status
- Window lift can be controlled either by multiple LIN salve nodes or LIN master node (through GUI)
- Able to comply with relevant content in US Federal Motor Vehicle Safety Standard (FMVSS No. 118)
