Abstract: An input circuit (20) and a method for protecting the input circuit (20) from positive and negative overvoltages. The input circuit (20) includes an N-channel Metal Oxide Semiconductor Field Effect Transistor (MOSFET) (12), a P-channel MOSFET (13), a Zener diode (21), and a diode-connected transistor (22). The P-channel MOSFET (13) protects the N-channel MOSFET (12) from negative overvoltages. The Zener diode (21) and the diode-connected transistor (22) protect the N-channel MOSFET (12) from positive overvoltages. In addition, the Zener diode (21) protects the P-channel MOSFET (13) from positive overvoltages.
