GENERAL DESCRIPTION

The ADM803/ADM809/ADM810 supervisory circuits monitor

the power supply voltage in microprocessor systems. They

provide a reset output during power-up, power-down, and

brownout conditions. On power-up, an internal timer holds

reset asserted for 240 ms. This holds the microprocessor in a

reset state until conditions have stabilized. The reset output

remains operational with V

ADM809 provide an active low reset signal ( RESET ), whereas

the ADM810 provides an active high signal (RESET) output.

The ADM809 and ADM810 have push-pull outputs, whereas

the ADM803 has an open-drain output, which requires an

external pull-up resistor.

Seven reset threshold voltage options are available, suitable for

monitoring a variety of supply voltages (see Table 3).

The reset comparator features built-in glitch immunity, making

it immune to fast transients on V

The ADM803/ADM809/ADM810 consume only 17 μA, making

them suitable for low power, portable equipment. The ADM803

is available in a 3-lead SC70; the ADM809/ADM810 are available

in 3-lead SOT-23 and 3-lead SC70 packages.
