Voltage detection type overcurrent protection device for class-D amplifier










Image Number 7 for United States Patent #7701287.

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.
