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 and +2.5 V systems.

SOT−23

TB SUFFIX

CASE 527AG

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

SC−70

CASE 419AB

guaranteed to be in the correct state at V 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.
