ABSTRACT:
A high impedance open circuit type of overvoltage protection circuit useful in conjunction with a SLIC is provided. Diodes are used to prevent current flow back into the SLIC. In addition, voltage-sensitive clamps are provided to clamp the SLIC current source and SLIC current sink into nonconductive states in the presence of an overvoltage condition.
