Valid RESET with V
CC
Under 1.0 V
To ensure that the CAX809 RESET pin is in a known state when V
CC
is under 1.0 V, a >10 kW pulldown resistor between
RESET
pin and GND is recommended. For the CAX810, a pullup resistor from RESET pin to V
CC
is needed.

Bidirectional Reset Pin Interfacing
The CAX809/810 can interface with mP/mC bidirectional reset pins by connecting a 4.7 kW resistor in series with the
CAX809/810 reset output and the mP/mC bidirectional reset pin.

CAX803 OpenDrain RESET Application
The CAX803 features an opendrain RESET output and
therefore needs a pullup resistor on the output for proper
operation, as shown on Figure 11. An advantage of the
opendrain output includes the ability to “wire AND”
several outputs together to form an inexpensive logic circuit.
It is also possible to have the pullup resistor connected to
a different supply which can be higher than the CAX803
V
CC
pin. The value of the pullup resistor is not critical in
most applications, typical values being between 5 kW and
10 kW.
