摘要：An exemplary circuit for generating dying gasp signals () includes a power lossdetecting circuit (), a Digital Signal Processor (DSP) (), a unipolar switch circuit (), and acapacitor (C). The power loss detecting circuit is used for detecting power loss statuses

and generating interrupt signals, and includes a first input end. The DSP is connected tothe power loss detecting circuit, and is used for generating dying gasp signals accordingto the interrupt signals. The unipolar switch circuit includes a second input end connectedto the first input of the power loss detecting circuit, and a first output end connected tothe DSP. The capacitor includes one end connected to the first output end of theunipolar switch circuit, and another end connected to ground.
