The present invention discloses a voltage detection type overcurrent protection device, which applies to the output stage of a CMOS Class-D audio amplifier. Generally, a Class-D audio amplifier is used to drive a high-load loudspeaker; therefore, it needs a high-current driver. When there is a short circuit in the load, the high current will burn out the driver stage. The present invention detects the output voltage to indirectly monitor whether the output current is too large. Once an overcurrent is detected, the output-stage transistor is turned off to stop high current lest the circuit be burned out.       Recently Added Patents Motorcycle head light device Quick record function in a smart pen computing system Multi-temperature and multi-texture frozen food microwave heating tray Display screen with a graphical user interface Ink cartridge Managing voicemail greeting based on location of wireless communication device Methods of fabricating semiconductor devices   Randomly Featured Patents Sheet-fed rotary printing press with digital imaging Methods and systems for allocating power to an electronic device Catalytic elements Steam boilers Method for recording on multi-layer phase-change optical discs Stored value accessors in shared memory regions Technique for depositing coatings by pyrolysis/decomposition of precursor gas or gases Peak-ahead FIFO for DVD system stream parsing Process for the polymerization of ethylene and the resulting products Process for the preparation of N,N-dimethyl-N-(2-bromo-4-methylphenyl)-triazene © 2006-2008 PatentGenius.
