CAT811/D
CAT811
4-Pin Microprocessor
Power Supply Supervisor
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.
