SMIC 0.18um Low Leakage VCC Detector
The present IP is a VCC Detector (VDT) circuit.
Overview
The present IP is a VCC Detector (VDT) circuit. It detects the voltage level of its power supplies, AV18 and AV33. The normal operation voltage levels of AV18 and AV33 are 1.62v~1.98v and 3.0v~3.6v respectively. When the detected voltage on AV18/AV33 increases across the detection level VR18/VR33, the corresponding output OUTP15/OUTP23 generates a high level logic. When the detected voltage on AV18/AV33 decreases below the detection level VF18/VF33, the corresponding output OUTP15/OUTP23 generates a low level logic. This system consists of two comparator sub-circuits and needs an external bandgap. 1.8V power must be ready when 3.3V power is detected, otherwise no correct output will appear. The output may be in a wrong voltage level during the power-up phase before the bandgap becomes stable, however, if the power supply’s rise time lasts longer than 5ms, this erroneous output will not happen again.
