DESCRIPTIOn

The CAT803, CAT809, and CAT80 are supervisory

circuits that monitor power supplies in digital systems. The

CAT803, CAT809, and CAT80 are direct replacements

for the MAX803, MAX809 and MAX80 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 40 ms after the power supply level

has risen above that level. The underlying floating gate

technology, AE

makes it possible to offer any custom reset threshold

value. Seven industry standard threshold levels are

offered to support +5.0V, +3.3V, +3.0V and +2.5V

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 CAT80 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

levels as low as .0V.

The CAT803, CAT809, and CAT80 are available in both

the compact 3-pin SOT-23 and SC-70 packages.
