NAME
FUNCTION
Backup Battery Input. If V CC falls below its reset threshold, and if V BATT > V CC , OUT

BATT
connects to BATT. If V CC rises above 1.01 x V BATT , OUT connects to V CC . Bypass BATT to
GND with a 0.1μF capacitor.
Active-Low Manual Reset Input. RESET asserts when MR is pulled low. RESET remains low

MR
for the duration of reset timeout period after MR transitions from low to high. Connect MR to
V CC or leave unconnected if not used. MR is internally connected to V CC through a 30k Ω
pullup resistor.
Power-Fail Comparator Input. Connect PFI to a resistive divider to set the desired PFI

threshold. The PFI input is referenced to an internal threshold V PFT , V PFT-HYS internal
hysteresis provides noise immunity. The power-fail comparator is powered from OUT.
Watchdog Timer Input. If WDI remains high or low for longer than the watchdog timeout

WDI
period (t WD ), the internal watchdog timer runs out and asserts WDO . The internal watchdog
clears when reset asserts or whenever WDI sees a rising or falling edge. To disable the
watchdog feature, leave WDI unconnected or three-state the driver connected to WDI.
Active-Low Low-Line Output. LL goes low when V CC falls to 2.5% above the reset threshold

LL
(Table 2). LL provides an early warning of V CC failure before reset asserts. Use this output
to generate a nonmaskable interrupt (NMI) to initiate an orderly shutdown routine when
V CC is falling.
Open-Drain Battery-Test Output. Pulses low for 1.3s every 24 hours during the battery

BATT_TEST voltage test. If V BATT < 2.6V, BATTOK deasserts low. See Figure 6 for providing additional
load during the battery test.
Active-High Reset Output. RESET asserts when V CC falls below the reset threshold or when

MR asserts and stays asserted for the reset timeout period after V CC rises above the reset
threshold and MR deasserts.

Battery-OK Output. BATTOK goes low when the battery voltage falls below the BATTOK
threshold (BATTOK is low when in battery-backup mode).
Active-High Battery-On Output. BATTON goes high when in battery-backup mode.
