DESCRIPTION
The CAT809 and CAT810 are µP supervisory circuits that monitor power supplies in digital systems. The CAT809 and CAT810 are direct replacements for the MAX809 and MAX810 in applications operating over the industrial temperature range.

FEATURES
■ Precision monitoring of
    +5.0 V (+/- 5%, +/- 10%, +/- 20%),
    +3.3 V (+/- 5%, +/ 10%),
    +3.0 V (+/- 10%) and
    +2.5 V (+/- 5%) power supplies
■ Offered in two output configurations:
    - CAT809: Active LOW reset
    - CAT810: Active HIGH reset
■ Direct replacements for the MAX809 and MAX810 in applications operating over the industrial temperature range
■ Reset valid down to VCC = 1.0 V
■ 6 µA power supply current
■ Power supply transient immunity
■ Compact 3-pin SOT23 and SC70 packages
■ Industrial temperature range: -40˚C to +85˚C
