Pin Function
Power-On Reset Threshold (Analog Input): Comparator input assigned to
battery-OK condition detection. When the level on this pin first exceeds
V
of 700ms and the /POF threshold output is deasserted.
Nonmaskable Interrupt Threshold (Analog Input): Voltage monitor input as-
signed to “low battery” condition detection. When the level on this pin falls
below V
Power-Off Threshold (Analog Input): Voltage monitor input assigned to
“dead battery” condition detection. When the level on this pin falls below
V
a reset cycle occurs (V
Ground: Power and signal return for all IC functions.
Power-off (Output): Active-low, open-drain output. Asserted and latched
when V
reset until the battery is replaced and a power-on reset cycle occurs.
Nonmaskable Interrupt (Output): Active-low, open-drain output. Asserted
when V
power system operation should not be allowed.
Reset (Output): Active-low, open-drain output. Asserted for a minimum of
700ms at power-on or anytime V
175ms minimum when RTH (/MR) is externally pulled low (manual reset).
(Analog Input): Power supply input.
