NXP Semiconductors FXTH8715 胎压监测传感器(TPMS)
飞思卡尔 FXTH8715 胎压监测传感器 (TPMS)是高度集成的 TPMS，并具有市场上最小的 7x7mm 的封装尺寸。这些器件具有最低的发射功耗（Idd 小于 8mA）。它们还具有目前市场上最大的内存（8kB）和独特的双轴加速度计结构。该 TPMS 解决方案集成了一个 8 位微控制器（MCU）、压力传感器、XZ 轴或 Z 轴加速度计和射频发射器。这些器件的测压范围为 100-1500kPa，支持中等和重型卡车、巴士和建筑车辆。TPMS 主要的市场驱动力是不断提高的安全和车队管理要求。
This TPMS solution integrates an 8-bit microcontroller (MCU), pressure sensor, XZ-axis or Z-axis accelerometer and RF transmitter. These devices, with pressure ranges from 100kPa to 1500kPa, supports medium and heavy duty trucks, buses, and construction vehicles.
