DEVICE IDENTIFICATION AND TEMPERATURE SENSOR CIRCUIT
摘要：
An integrated circuit includes a device identification circuit and a temperature sensor diode connected in parallel from a common node. The device identification circuit includes a resistor connected to a diode-connected transistor. The device identification circuit and the temperature sensor diode are adapted to not be simultaneously operating in an ON state. A first voltage is applied to the common node to place the device identification circuit in an ON state and place the temperature sensor diode in an OFF state to identify the integrated circuit. A second voltage is applied to the common node to place the device identification circuit in an OFF state and place the temperature sensor diode in an ON state to determine a temperature of the integrated circuit.
摘要（中）：

集成电路包括从公共节点并联连接的器件识别电路和温度传感器二极管。 器件识别电路包括连接到二极管连接的晶体管的电阻器。 设备识别电路和温度传感器二极管适于不处于ON状态。 将第一电压施加到公共节点以将器件识别电路置于ON状态，并将温度传感器二极管置于OFF状态以识别集成电路。 将第二电压施加到公共节点以将设备识别电路置于OFF状态，并将温度传感器二极管置于ON状态以确定集成电路的温度。
