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.
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. 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.
三不主义
The CAT809 features a RESET push-pull output (active LOW) and the CAT810 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.学校封闭式管理
The CAT809/810 are fully specified over the industrial temperature range (-40˚C to 85˚C) and are available in compact 3-pin SOT23 and SC70 packages.
