VALID RESET WITH V
To ensure that the CAT811 RESET
state when V
resistor
recommended; the value is not critical. For the
CAT812, a pull-up resistor from RESET pin to V
needed.
Figure 3. RESET
BI-DIRECTIONAL RESET PIN INTERFACING
The CAT811/812 can interface with µP/µC bi-
directional reset pins by connecting a 4.7kΩ resistor in
series with the CAT811/812 reset output and the
µP/µC bi-directional reset pin.
