                     The invention is directed to a high voltage detection circuit best illustrated by                     
                     Independent claim 1 as reproduced as follows:                                                         
                     1.  A voltage detector circuit which discriminates between a high voltage                             
                     input signal and a lower input voltage without creating an excessive field                            
                     across the gate oxide of a sensing transistor, comprising:
