ABSTRACT:
A high voltage tolerant (“HVT”) power up detector. The HVT power up detector includes a voltage detector circuit coupled to a high voltage tolerant transistor (“HVTT”). The voltage detector circuit determines when a voltage supply is above a threshold logic level voltage. The HVTT has a gate coupled to receive a logic level voltage and a source and a drain to couple between the voltage supply and the voltage detector circuit. The HVTT shelters the voltage detector circuit from voltages above the logic level voltage when the voltage supply exceeds the logic level voltage.
