ABSTRACT:
A signal distribution circuit subject to high-level reverse-current transients is protected by the combination of a reverse-current sensor and a controlled current shunt. The sensor detects a potentially damaging reverse-current current surge and sends a control signal to the current shunt. The current shunt then diverts the surge away from the distribution amplifier which consequently can have a low power rating. After the transient subsides, the circuit is automatically reset to allow continuation of normal signal distribution.
