AX6901/2/3/4   3-Pin Microprocessor Reset Circuits 

性能描述：
       TheAX6901/2/3/4 is used  for  microprocessor  (µP)  supervisory  circuits  to  monitor  the
power  supplies  in  µP  and  digital  systems.  They  provide  excellent  circuit  reliability  and  low cost by eliminating external components and adjustments when used with +5V, +3.3V, +3.0V, +2.5V powered circuits.These circuits perform a single function: they assert a reset signal whenever the VCC supply  voltage  declines  below  a  preset  threshold,  keeping  it  asserted  for  at  least  200ms after VCC has risen above the reset threshold. Reset thresholds suitable for operation with a  variety  of  supply  voltages  are  available.  TheAX6901/2/3/4 has  push  pull  outputs.        

         TheAX6901/3 has  an  active  low  RESET  output,  while  theAX6902/4  has  an  active  high RESET output. The reset comparator is designed to ignore fast transients on VCC, and the
outputs are guaranteed to be in the correct logic state for VCC down to 1.0V. Low supply
current  makes  theAX6901/2/3/4  ideal  for  use  in  portable  equipment.  TheAX6901/2/3/4  is available in a 3-pin SOT23 and SC70 package.
