一种PWM通信非接触式角度传感电路
摘要：
本实用新型公开了一种PWM通信非接触式角度传感电路，所述主霍尔电源滤波模块的输入端用于连接电源，所述主霍尔电源滤波模块的输出端经主霍尔输入端的ESD防护模块后与双路霍尔式角度传感模块连接，所述双路霍尔式角度传感模块经主霍尔输出端的ESD防护模块后与主霍尔PWM信号滤波模块连接；所述副霍尔电源滤波模块的输入端用于连接电源，所述副霍尔电源滤波模块的输出端经副霍尔输入端的ESD防护模块后与双路霍尔式角度传感模块连接，所述双路霍尔式角度传感模块经副霍尔输出端的ESD防护模块后与副霍尔PWM信号滤波模块连接，以实现AMT换挡器P挡、R挡、N挡、D挡位识别，以PWM通信的方式输出当前挡位数据，避免由输出短路、过压、ESD带来的问题。
摘要（英）：

The utility model discloses a PWM communication non -contact angle detection circuit, main hall power filter module's input is used for connecting, main hall power filter module's output is connected with double - circuit hall formula angle sensing module behind the ESD protection module of main hall input, double - circuit hall formula angle sensing module is connected with main hall PWM signal filtering module behind the ESD protection module of main hall output, vice hall power filter module's input is used for connecting, vice hall power filter module's output is connected with double - circuit hall formula angle sensing module behind the ESD protection module of vice hall input, double - circuit hall formula angle sensing module is connected with vice hall PWM signal filtering module behind the ESD protection module of vice hall output to realize that AMT selector P keeps off, R keeps off, N keeps off, D keeps off the bit identification, with the current figure place certificate of keeping off of the mode output of PWM communication, avoid the problem of bringing by output short circuit, excessive pressure, ESD.
