  • Fault-protected analog and digital input/output interface
    Patent number: 11967816
    Abstract: An input/output (I/O) interface includes a resistance-to-current (R/I) converter; an internal resistor; first, second, and third current sources; first and second diodes; and a comparator. The R/I converter is coupled to an I/O pin and generates an output current based on an external resistance at the I/O pin during an analog operating mode. The internal resistor is coupled to the I/O pin and to ground. The first current source is coupled to the R/I converter circuit. The first diode is coupled to the R/I converter and to the I/O pin. The second current source is coupled to the R/I converter and the first diode and to ground. The second diode is coupled to the I/O pin and to the third current source. The comparator has inputs coupled to the I/O pin and to a reference voltage, and outputs a control signal indicative of a digital operating mode.
