  英飞凌科技股份公司将自身在汽车领域经验证的专业知识与面向汽车胎压监测系统(TPMS)市场的专利玻璃-硅-玻璃MEMS硅麦传感器结合,推出XENSIV™ SP49胎压监测传感器。该传感器集成了MEMS传感器与ASIC,可提供先进的胎压监测系统所需的智能轮胎功能。XENSIV™ SP49胎压监测传感器采用性能强大的 32位Arm® M0+内核、大容量闪存和 RAM,并具有低功耗监测(LPM)以及更优化的快速加速度感应功能,适用于轮胎位置自动检测、轮胎充气辅助、爆胎检测、负载检测等智能轮胎功能。

英飞凌推出具有智能功能的XENSIV™轮胎压力传感器

  SP49 是英飞凌上一代 SP40 TPMS 新一代产品,与SP40引脚对引脚兼容,配备硬件主/从 I²C接口及软件模拟 UART、SPI 和 PWM 接口,适用于1 GHz 以下频率,并可扩展以用于 BLE TPMS。这款传感器达到ASIL-A级标准,集成度高且经过优化,具备现代TPMS模块所需的所有功能。SP49集成了微控制器、传感器和便捷的外设,因此只需要少量无源元件,即可构成完整的TPMS传感器单元。该半导体器件采用低功耗设计,是电池供电应用的理想选择。

  除了能够利用内部集成的间隔计时器实现唤醒功能外,SP49传感器还适用于需要低功耗的独立远程压力传感解决方案。在这些应用中,该款具有唤醒功能和一流灵敏度的低频接收器能够实现按需测量。
