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

Bi−directional Reset Pin Interfacing
The CAT809/810 can interface with mP/mC bi−directional reset pins by connecting a 4.7 kW resistor in series with the
CAT809/810 reset output and the mP/mC bi−directional reset pin.

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
a different supply which can be higher than the CAT803 V
CC
pin. The value of the pull−up resistor is not critical in most
applications, typical values being between 5 kW and 10 kW.
