Antminer L7 hash board troubleshooting about the temp sensing circuit

L7 hash board has 4 temperature sensing circuits, which are mainly composed of a temperature sensing chip and a corresponding ASIC chip. This video mainly explains the circuit structure of these four circuits, and how to measure the working voltage of the input pin and powering pin. Among them, the working principles of the 1st and 3rd circuits are the same, and the remaining 2 temperature sensing circuits are the same.
