The ADM809 series Supervisory Circuit which monitors the power supply voltage in microprocessor systems. It provides a reset output during power-up, power-down and brownout conditions. On power-up, an internal timer holds reset asserted for 240ms. This holds the microprocessor in a reset state until conditions have stabilized. The reset output remains operational with VCC as low as 1V. The ADM803 and ADM809 provide an active low reset signal (RESET). The ADM809 and ADM810 have push-pull outputs. The reset comparator features built-in glitch immunity, making it immune to fast transients on VCC.
● Specified over-temperature
● 17µA Low power consumption
● Reset assertion down to 1V VCC
● 140ms Minimum power-ON reset
