Patent ID: 8283954

Claim:
A resume and reset (RSMRST) signal output circuit, for outputting a low level voltage RSMRST signal, comprising: a first switch circuit configured to receive a first voltage signal and convert the first voltage signal to a second voltage signal; a delay circuit configured to be charged by the second voltage signal and output the second voltage signal once fully charged; and a second switch circuit configured to receive the second voltage signal and output the RSMRST signal; wherein the delay circuit is charged during a first state and discharged during a second state; in the first state, the first switch circuit is configured to receive a low level voltage first voltage signal, the delay circuit is charged by the second voltage signal and the second switch circuit is configured to output a high level voltage RSMRST signal once the delay circuit is fully charged; in the second state, the first switch circuit is configured to receive a high level voltage first voltage signal, the delay circuit is discharged by the first switch circuit and the second switch circuit is configured to output the low level voltage RSMRST signal.
