Pin Description
Pin Number
Pin Name
Pin Function
1
RTH(/MR)
Power-On Reset Threshold (Analog Input): Comparator input assigned to
battery-OK condition detection. When the level on this pin first exceeds
V
REF
, the reset generator cycles. The /RST output is held low for a minimum
of 700ms and the /POF threshold output is deasserted.
2
NTH
Nonmaskable Interrupt Threshold (Analog Input): Voltage monitor input
assigned to
“
low battery
”
condition detection. When the level on this pin falls
below V
REF
, the /NMI output is asserted.
Power-Off Threshold (Analog Input): Voltage monitor input assigned to
“
dead battery
”
condition detection. When the level on this pin falls below
V
REF
, the /RST
and /POF outputs are asserted. The condition is latched until
a reset cycle occurs (V
RTH
> V
REF
).
Ground: Power and signal return for all IC functions.

PTH
4
GND
5
/POF
Power-off (Output): Active-low, open-drain output. Asserted and latched
when V
PTH
< V
REF
, which is a
“
dead battery
”
condition. The system is held
in reset until the battery is replaced and a power-on reset cycle occurs.
6
/NMI
Nonmaskable Interrupt (Output): Active-low, open-drain output. Asserted
when V
NTH
< V
REF
, which is a
“
low battery
”
condition. This indicates high-
power system operation should not be allowed.
7
/RST
Reset (Output): Active-low, open-drain output. Asserted for a minimum of
700ms at power-on or anytime V
PTH
drops below V
REF
. Also asserted for
175ms minimum when RTH (/MR) is externally pulled low (manual reset).
8
VDD
(Analog Input): Power supply input.
