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 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, AE2(TM) used by Catalyst 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 SOT143 package.

Name Description
GND Ground
RESET
RESET
Active LOW reset. RESET is asserted if VCC falls below the reset threshold
and remains low for at least 140ms after VCC rises above the reset threshold.
Active HIGH reset. RESET is asserted if VCC falls below the reset
threshold and remains high for at least 140ms after VCC rises above
the reset threshold.
MR Manual Reset Input. A logic LOW on MR asserts RESET. RESET remains
active as long as MR is LOW and for 140ms after MR returns HIGH. The
active low input has an internal 20kpull-up resistor. The input should be left
open if not used. It can be driven by TTL or CMOS logic or shorted to ground
by a switch.
VCC Power supply voltage that is monitored.
