the reset and watchdog timeout periods, and

PIN ASSIGNMENTS
Pin 1 — V BATT — Battery-Backup Input. Con-
nect to the external battery supply or super-
charging capacitor and charging circuit. If a
backup battery is not provided, connect this
pin to ground.
Pin 2 —V OUT — Output Supply Voltage. V OUT
connects to V CC when V CC is greater than
V BATT and V CC is above the reset threshold.
When V CC falls below V BATT and V CC is
below the reset threshold, V OUT connects to
V BATT . Connect a 0.1 μ F capacitor from V OUT
to GND.
Pin 3 — V CC — +5V Input Supply Voltage.
Pin 4 — GND — Ground reference for all
signals.
Pin 5 — BATT ON — Battery On Output. Goes
high when V OUT switches to V BATT . Goes low
when V OUT switches to V CC . Connect the
base of a PNP through a current-limiting
resistor to BATT ON for V OUT current
requirements greater than 250mA.
Pin 6 — LOWLINE — Low Line Output. This
output pin goes LOW when V CC falls below
the reset threshold voltage. This output pin
returns to its HIGH output as soon as V CC
rises above the reset threshold voltage.
internal oscillator sets the reset delay and
watchdog timeout period. When OSC SEL is
driven LOW, the external oscillator input
pin, OSC IN , is enabled (refer to Table 1 ).
This input pin has a 10 μ A internal pull-up.
Pin 9 — PFI — Power-Fail Input. This is the
noninverting input to the power-fail
comparator. When PFI is less than 1.25V,
PFO goes low. Connect PFI to GND or
V OUT when not used.
Pin 10 — PFO — Power-Fail Output. This is
the output of the power-fail comparator.
PFO goes low when PFI is less than 1.25V.
This is an uncommitted comparator, and
has no effect on any other internal circuitry.
Pin 11 — WDI — Watchdog Input. This is a
three-level input pin. If WDI remains either
HIGH or LOW for longer than the watchdog
timeout period, WDO goes LOW and RESET
is asserted for the reset timeout period. WDO
remains LOW until the next transition at this
input pin. Leaving this input pin unconnected
disables the watchdog function. This input
pin connects to an internal voltage divider
between V OUT and ground, which sets it to
mid-supply when left unconnected.
