C+
Charge-Pump Capacitor Positive Connection
13
LBI
Low-Battery Detector Input.
LBO
goes low when V
LBI
drops below V
REF
. Connect LBI to the center of a
resistor voltage divider between BATT and GND.
15
LBO
Low-Battery Output. Open-drain output of the Low-Battery Detector Comparator.
LBO
is high impedance
when device is shutdown or V
LBI
> V
REF
. V
LBO
is low when V
LBI
< V
REF
. Typically, connect a 200k
pull-
up resistor between
LBO
and OUT2.

LBHYS
Low-Battery Detector Hysteresis Control. An open-drain output to set the hysteresis of the Low-Battery
Detector Comparator.
11
C-
Charge-Pump Capacitor Negative Connection
12
DGND
Digital Ground

Power Ground
NAME
FUNCTION
1
LX
Inductor Input. Drain of the internal p-channel MOSFET.
PIN
16
RESET
Reset Output.
RESET
remains low during initial power-up for 75ms after OUT2 is ready.
RESET
has an
internal 10k
pull-up resistor connected to OUT2.
RESET
is valid for V
BATT
down to 1V.
17
IN2
Linear Regulator 2 Power-Supply Input
18
OUT2
Linear Regulator 2 Output. Bypass with a 2.2μF, low-ESR capacitor to GND. Up to 200mA is available from
OUT2. The reset circuit monitors this voltage.
19
