DESCRIPTION

The CAT811 and CAT812 are µP supervisory circuits

that monitor power supplies in digital systems. The

CAT811 and CAT812 are direct replacements for the

MAX811andMAX812inapplicationsoperatingoverthe

industrial temperature range; both have a manual reset

input.

offered to support +5.0 V, +3.3 V, +3.0 V and +2.5 V

systems.

The CAT811 features a RESET push-pull output (active

LOW) and the CAT812 features a RESET push-pull

output (active HIGH).

Fast transients on the power supply are ignored and the

output is guaranteed to be in the correct state at V_cc

levels as low as 1.0 V.

level and for at least 140 ms after the power supply level

has risen above that level. The underlying floating gate

technology, AE^2(TM)used by Catalyst Semiconductor,

makes it possible to offer any custom reset threshold

value. Seven industry standard threshold levels are

The CAT811/812 are fully specified over the industrial

temperature range (-40˚C to 85˚C) and are available in

a compact 4-pin SOT143 package.
