The  MAX809  and  MAX810  are  cost-effective  system  supervisor circuits  designed  to 
monitor VCC in  digital systems and provide  a reset signal to the host processor when 
necessary.  No  external  components are  required. The  reset  output  is  driven  active 
within ~200msec of VCC falling through the reset voltage threshold. Reset is maintained 
active  for  a timeout  period  which is  trimmed  by  the  factory  after  VCC  rises  above the 
reset threshold. The MAX810 has an active-high RESET output while the MAX809 has 
an  active-low  RESET  output.  Both  devices are  available  in  SOT-23  and  SC-70 
packages. The MAX809/810  are optimized to reject  fast  transient  glitches on the VCC 
line. Low supply current of 0.5 A (VCC = 3.2 V) makes these devices suitable for battery 
powered applications.
