Abstract
The present disclosure discloses an electrical discharge circuit. A voltage-dividing circuit performs voltage division on a voltage input terminal. A detection circuit generates a boosted detection signal. A first inverter is coupled to a first voltage feeding terminal and a second inverter input terminal. A second inverter is coupled to a first inverter output terminal and a ground terminal. A capacitor circuit of a RC circuit is coupled to the first voltage feeding terminal through a resistor to be charged to provide electric charges to the inverter input terminals. A first switch circuit is coupled to one of the inverter input terminals and the ground terminal. The boosted detection signal turns on and off the first and the second switch circuits respectively when an ESD input occurs such that a first and a second discharge transistors controlled by the inverter output terminals turn on to discharge the voltage input terminal.
