The SMIC0.13um Voltage Detector detects the voltage level of its power supply AVDDH. The normal operation voltage levels of AVDDL and AVDDH are 1.08v~1.32v and 3.0v~3.6v respectively. When the detected voltage AVDDH increases across the detection level VR33, the output OUT is generated as a high level logic. When the detected voltage AVDDH decreases across the detection level VF33, the corresponding output OUT is generated as a low level logic. This system contains one comparator sub-circuit; the voltage reference and bias come from S13V33_PRG_14. The output may be in wrong voltage level during the power-up phase before the voltage reference (bandage) becomes stable.
