Abstract
This invention provides an automatic current interruption to protect the audio power amplifier circuitry when current conditions above the capacity of the power amplifier are encountered. The circuit monitors the current supplied to the power amplifier and utilizes a transistor to interrupt power amplifier output. Power output is latched in its interrupted state until reset and is capable of quickly and effectively shutting down power supply output.
