CAT811
Voltage Supervisor, 4-Pin,
Push-Pull, Active Low, with
Manual Reset
Description
The CAT811 is a microprocessor supervisory circuit that monitors
power supplies. The CAT811 is a direct replacement for the MAX811
in applications operating over the industrial temperature range and has
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).
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 is fully specified over the industrial temperature range
(−40°C to 85°C) and is available in a compact 4−pin SOT−143
package.

Active LOW reset. RESET is asserted if V
CC
falls below the reset threshold and remains low for at
least 140 ms after V
CC
rises above the reset threshold.
Manual Reset Input. A logic LOW on MR asserts RESET. RESET remains active as long as MR is
LOW and for 140 ms after MR returns HIGH. The active low input has an internal 20 kW pull−up resis-
tor. The input should be left open if not used.
