  • Integrated power-ground reverse wiring protection circuit
    Patent number: 11133143
    Abstract: A two-wire current loop system includes a current loop with a transmitter and a host. The system also includes a monolithic integrated circuit included with the transmitter. The monolithic integrated circuit includes: 1) a power supply terminal coupled to the current loop; 2) a loop ground terminal coupled to the current loop and configured to output a current to the current loop; 3) device circuitry with a power supply node and an internal ground node, wherein the power supply node is coupled to the power supply terminal; and 4) a reverse wiring protection circuit coupled between the internal ground node of the device circuitry and the loop ground terminal.
