    產(chǎn)品信息

    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 reset input.
    These devices generate a reset signal, which is asserted while the power supply voltage is below a preset threshold level and for at least 140 ms after the power supply level has risen above that level. The underlying floating gate technology, Analog EEPROM used by ON Semiconductor, makes it possible to offer any custom reset 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
    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
    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.
    • 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:
    • - CAT811: Active LOW reset
    • - CAT812: Active HIGH reset
    • Manual reset input
    • Direct replacements for the MAX811 and MAX812 in applications operating over the industrial temperature range
    • Reset valid down to V
    • = 1.0 V
    • 6 μA power supply current
    • Power supply transient immunity
    • Compact 4-pin SOT143 package
    • Industrial temperature range: -40°C to +85°C
