APPLICATION INFORMATION
5.3
Using in PIC ? Microcontroller,
This section shows application related information that
may be useful for your particular design requirements.
Note:
ICSP? Applications
This operation can only be done using the
5.1
Supply Monitor Noise Sensitivity
device with the Open-Drain RST pin
The MCP131X/2X devices are optimized for fast
response to negative-going changes in V DD . Systems
with an inordinate amount of electrical noise on V DD
(such as systems using relays) may require a 0.01 μF
or 0.1 μF bypass capacitor to reduce detection
sensitivity. This capacitor should be installed as close
to the MCP131X/2X as possible to keep the capacitor
lead length short.
0.1 μF
(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.
Figure 5-4 shows the typical application circuit for using
the MCP132X for a voltage supervisory function when
the PIC ? microcontroller will be programmed via the In-
Circuit Serial Programming? (ICSP?) feature. Addi-
tional information is available in TB087, “Using Voltage
Supervisors with PIC ? Microcontroller Systems which
Implement In-Circuit Serial Programming? ”
(DS91087).
