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 MAX811 and MAX812 in applications operating over the industrial temperature range; both have a manual ret input.
The devices generate a ret signal, which is asrted while the power supply voltage is below a pret threshold level and for at least 140 ms after the power supply level has rin above that level. 梨子英语怎么说
The underlying floating gate technology, AE2(TM) ud by Catalyst Semiconductor, makes it possible to offer any custom ret threshold value. Seven industry standard threshold levels are 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.
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.
