TWO OUTPUT PIN PROTOCOL FOR SPEED, DIRECTION, AND DIAGNOSIS

The disclosure relates to two output pin protocol for speed, direction, and diagnosis. A sensor device includes a first sensor element that generates a first sensor signal based on a varying magnetic field; a second sensor element that generates a second sensor signal based on the varying magnetic field; a signal processing circuit configured to generate a first pulsed signal based on the first sensor signal and generate a second pulsed signal based on the second sensor signal; a fault detector that detects a fault and generates an error signal indicating the fault; and an output generator that receives the error signal based on a first condition that the fault detector detects the fault, and simultaneously outputs a first output signal and a second output signal. In response to the first condition being satisfied, the output generator maintains the first output signal in a steady state and outputs the second pulsed signal as the second output signal. 本公开涉及用于速度、方向和诊断的双输出引脚协议。例如，一种传感器设备，包括：第一传感器元件，基于变化磁场生成第一传感
