This section shows application related information that
may be useful for your particular design requirements.
5.1
The MCP131X/2X devices are optimized for fast
response to negative-going changes in V
with an inordinate amount of electrical noise on V
(such as systems using relays) may require a 0.01 µF
or 0.1 µF bypass capacitor to reduce detection sensitiv-
ity. This capacitor should be installed as close to the
MCP131X/2X as possible to keep the capacitor lead
length short.

This operation can only be done using the
device with the Open-Drain RST pin
(MCP1320, MCP1321, and MCP1322).
Devices that have the internal pull-up
resistor are not recommended due to the
current path of the internal pull-up resistor.
It is recommended that the current into the
RST pin be current limited by a 1 kΩ
resistor.
