APPLICATIONS
A typical operating Circuit is shown in Figure 15. The unregu-
lated dc input supply is monitored using the PFI input via the
resistive divider network. Resistors R1 and R2 should be selected
such that when the supply voltage drops below the desired level
(e.g., 5 V) the voltage on PFI drops below the 1.25 V threshold
thereby generating an interrupt to the
μ
P. Monitoring the
preregulator input gives additional time to execute an orderly
shutdown procedure before power is lost.
