Patent ID: 7536492

Claim:
An apparatus to reset an Inter-Integrated Circuit (I2C) bus slave, the apparatus comprising: the I2C bus slave communicating over a data line and a clock line of an I2C bus; a sinking current detector detecting a one milliamp current in the data line and the clock line, wherein the sinking current detector comprises a ten ohm data line resistor in series with the data line; a ten ohm clock line resistor in series with the clock line; a data line differential amplifier detecting a 0.01 volt first specified voltage across the data line resistor; a clock line differential amplifier detecting a 0.01 volt second specified voltage across the clock line resistor; a timer module detecting the first and second specified voltage in the data line and the clock line for a five millisecond time interval; and a reset module resetting the I2C bus slave in response to the timer module detecting the five millisecond time interval of the first and second specified voltage.
