Low-Cost Microprocessor Supervisory
Circuits with Battery Backup
Using the Power-Fail Comparator
to Assert Reset
In addition to asserting reset at the V CC reset threshold
voltage, reset can also be asserted at the PFI input
pulse when the monitored supply drops below a user-
specified threshold or when V CC falls below the reset
threshold. For additional noise rejection, place a
capacitor between PFI and GND.
threshold voltage. Connect PFO to MR to initiate a reset
