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 6. 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
is not critical in most applications, typical values being
between 5kΩ and 10kΩ.
