The ADM803 supervisory circuit 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 provides an active-low reset signal RESET, and has an open-drain output stage which requires an external pull-up resistor. Seven reset threshold options are available. The reset comparator features built-in glitch immunity, making it immune to fast transients on VCC. The ADM803 is available in 3-lead SC70 and consumes only 17µA, making it suitable for low power portable equipment.
