CAT803, CAT809, CAT810
3-Pin Microprocessor
Power Supply Supervisors
Description
The CAT803, CAT809, and CAT810 are supervisory circuits that
monitor power supplies in digital systems. The CAT803, CAT809, and
CAT810 are direct replacements for the MAX803, MAX809 and
MAX810 in applications operating over the industrial temperature range.
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 a nd +2. 5 V systems.
The CAT803 has an open ? drain RESET output (active LOW). The
CAT803 requires a pull ? up resistor on the reset output.
The CAT809 features a push ? pull RESET output (active LOW) and
the CAT810 features a push ? pull RESET output (active HIGH).
Fast transients on the power supply are ignored and the output is
guaranteed to be in the correct state at V CC levels as low as 1.0 V.
The CAT803, CAT809, and CAT810 are available in both the
compact 3 ? pin SOT ? 23 and SC ? 70 packages.
