Abstract
An I2C MUX with an anti-lock device comprises an I2C multiplexer (I2C MUX) and a reset unit. The I2C MUX is used to connect with a system, which has a central processing unit (CPU), an I2C main control unit, and a plurality of I2C elements. The reset unit is connected to the CPU and the I2C MUX. The I2C main control unit emits a signal to the CPU, and the CPU then sends an open-circuited signal to the reset unit. The reset unit sends a reset signal to the I2C MUX to reconnect the I2C MUX with one of the multiple normal I2C elements and the I2C main control unit when the connection between the chosen I2C element, the I2C MUX and the I2C main control unit is broken.
