CAT811, CAT812
4-Pin Microprocessor
Power Supply Supervisors
with Manual Reset
Description
V CC
The CAT811 and CAT812 are microprocessor supervisory circuits
that monitor power supplies. 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 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 Vcc 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 SOT ? 143
package.
