Abstract: A circuit for status monitoring, and fault recovery and isolation for an I2C bus is provided. The I2C bus is electrically connected to a master device and a plurality of slave devices. Each of the slave devices has an address. The circuit includes a receiver unit, a decoder unit, and a troubleshooting unit. The receiver unit can receive a data signal and a clock signal that are transmitted from the master device to the I2C bus. The decoder unit is configured to obtain address information and a read/write bit based on the data signal and the clock signal. The troubleshooting unit is configured to, when the troubleshooting unit determines that a target slave device is malfunctioning based on the data signal, the clock signal, and the read/write bit, identify the target slave device based on the address information, and perform a troubleshooting operation on the target slave device.
