                                                                                           ACE809                                               Technology Description 3-Pin Microprocessor Reset Circuits The ACE809 microprocessor supervisory circuits can be used to monitor the power supplies in microprocessor and digital systems. They provide s reset to the microprocessor during power-up, power-down and brown-out conditions. The function of the ACE809 is to monitor the VCC supply voltage, and assert a reset signal whenever this voltage declines below the factory-programmed reset threshold. The reset signal remains asserted for 240ms after VCC rises above the threshold. The ACE809 has an active-low RESET output. The output of the ACE809 is guaranteed valid down to VCC =1V.
