CAX803, CAX809, CAX810
3-Pin Microprocessor
Power Supply Supervisors
Description
The CAX803, CAX809, and CAX810 are supervisory circuits that
monitor power supplies in digital systems. The CAX803, CAX809,
and CAX810 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 and +2.5 V systems.
The CAX803 has an openâdrain RESET output (active LOW). The
CAX803 requires a pullâup resistor on the reset output.
The CAX809 features a pushâpull RESET output (active LOW) and
the CAX810 features a pushâpull RESET 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 CAX803, CAX809, and CAX810 are available in the compact
3âpin SOTâ23 package.
