具有单一诊断输出的多通道故障检测
摘要：
本公开涉及具有单一诊断输出的多通道故障检测。例如，具有单个诊断状态管脚的多通道设备可以被配置为检测一个或多个通道是否具有故障。可以在系统内操作的多通道设备可以仅使用单个诊断状态管脚而不利用附加的诊断控制管脚来传输多个通道中的哪个通道具有故障。多通道设备可以在诊断状态管脚上输出故障信号，并且响应于与故障通道相同的通道上的询问输入信号，向系统指示哪个通道是故障通道。
摘要（英）：

A multi-channel device with a single diagnosis status pin may be configured to detect if one or more channels has a fault. The multi-channel device, which may operate within a system, can communicate which channel, of a plurality of channels, has the fault using only a single diagnosis status pin and no additional diagnosis control pins. The multi-channel device may output a fault signal on the diagnosis status pin and in response to an interrogation input signal on the same channel as a fault channel indicate to the system which channel is the fault channel.
