FUNCTION
Supply Voltage Input. Bypass V CC to GND with a 0.1μF capacitor.
Backup Battery Input. If V CC falls below its reset threshold, and if V BATT > V CC , OUT 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 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 V PFT threshold. A 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 period (t WD ),
the internal watchdog timer runs out and a reset pulse is triggered for the reset timeout period. 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-High Battery-On Output. BATTON goes high when in battery-backup mode.
Active-Low Power-Fail Comparator Output. PFO goes low when V PFI falls below the internal V PFT
threshold and goes high when V PFI rises above V PFT + V PFT-HYS hysteresis.
Ground
Active-Low Reset Output. RESET asserts when V CC falls below the reset threshold or MR is pulled low.
RESET remains low for the duration of the reset timeout period after V CC rises above the reset threshold
and MR goes high. RESET also asserts low when the internal watchdog timer runs out.
Switched Output. OUT is connected to V CC when the reset output is not asserted or when V CC is
greater than V BATT . OUT connects to BATT when RESET is asserted and V BATT is greater than V CC .
Bypass OUT to GND with a 0.1μF (min) capacitor.
