Abstract

An apparatus, system, and method are disclosed for resetting an inter-integrated circuit (I2C) bus slave. A data line resistor in series is provided with a data line of an I2C bus in communication with the I2C bus slave. A clock line resistor in series is provided with a clock line of the I2C bus. A data line differential amplifier detects a first specified voltage across the data line resistor and a clock line differential amplifier detects a second specified voltage across the clock line resistor wherein the first specified voltage is substantially equal to a data line resistor resistance multiplied by a specified current and the second specified voltage is substantially equal to a clock line resistor resistance multiplied by the specified current. A time module detects the first and second specified voltage for a specified time interval. A reset module resets the I2C bus slave in response detecting the first and second specified voltage for the specified time interval.
