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 VCC as low as 1 V. The ADM803 and  
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 VCC  
.
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.  
RESET  
ADM809 provide an active low reset signal (  
), 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.
