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.

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

Detailed Descriptions
Reset Timing
The reset signal is asserted LOW for the CAT803/CAT809 and HIGH for the CAT810 when the power supply voltage falls below
the threshold trip voltage and remains asserted for at least 140 ms after the power supply voltage has risen above the threshold.

= 25°C
The CAT803/CAT809/CAT810 protect mPs against
brownout failure. Short duration transients of 4 msec or less
and 100 mV amplitude typically do not cause a false RESET.
Figure 7 shows the maximum pulse duration of negative−

As the amplitude of the transient goes further below the
CAT809Z
threshold (increasing V − V ), the maximum pulse

Valid RESET with VCC Under 1.0 V
To ensure that the CAT809 RESET pin is in a known state when V is under 1.0 V, a >10 kW pull−down resistor between
CC
RESET pin and GND is recommended. For the CAT810, a pull−up resistor from RESET pin to V is needed.

CAT803 Open−Drain RESET Application
The CAT803 features an open−drain RESET output and
therefore needs a pull−up resistor on the output for proper
operation, as shown on Figure 11. An advantage of the
open−drain output includes the ability to “wire AND”
several outputs together to form an inexpensive logic circuit.
It is also possible to have the pull−up resistor connected to
