MC33912: 带DC电动机预驱动器和电流检测的LIN SBC

33912是一个由串行外设接口(SPI)控制的系统基础芯片(SBC)，结合了许多基于MCU的系统中经常使用的功能，以及一个本地互连网(LIN)收发器。33912拥有一个5.0V – 50mA的低压差稳压器，具有全面的保护和报告功能。此器件具有SPI完全可读的诊断功能和可选择的定时看门狗，用来监测错误操作。符合LIN协议规范2.0和2.1 ('G5AC)的LIN收发器，具有波形整形电路，较高的数据传输速率时可禁用波形整形电路。带有输出保护功能的两个60mA高边开关和两个160ma低边开关，可驱动电阻和电感负载。可对所有输出进行脉宽调制(PWM)。提供4个高压输入，可用于触点监控或者作为外部唤醒输入。这些输入能够用作高压模拟输入。这些引脚上的电压按比率分配，比率可选择，并通过模拟复用器提供。 33912有3个主要的工作模式：正常模式(提供所有功能)、睡眠模式(VDD关闭、通过LIN、唤醒输入(L1-L4)、循环传感和强制唤醒来实施唤醒)，停止模式(VDD开启，带有限的电流功能，通过CS、LIN总线、唤醒输入、循环传感、强制唤醒和外部复位来实施唤醒)。 33912符合LIN协议规范2.0、2.1 (‘G5AC)和SAEJ2602-2 (‘G5AC)。
