Update: 30 September, 2023

The LM80 is an I2C interface that monitors microprocessor system hardware. It can measure temperature, voltage, fan speed, etc., and has watchdog comparison functions, which can monitor and reset external circuits. It is suitable for both linear and digital temperature sensors, and it has a 2.8V to 5.75V power supply voltage range, low power supply current and I2C interface, so it can be widely used in personal computers, electronic test equipment and office electronic devices.
