Abstract
A resume and reset (RSMRST) signal output circuit, for outputting a low level voltage RSMRST signal, includes a first switch circuit, a delay circuit, and a second switch circuit. The first switch circuit receives a first voltage signal and converts the first voltage signal to a second voltage signal. The delay circuit is charged by the second voltage signal and outputs the second voltage signal it is when fully charged. The second switch circuit receives the second voltage signal and outputs the low level voltage RSMRST signal. The delay circuit is charged during a first state and discharged during a second state.
