LBO
Open−Drain Low−Battery Detector Output. Output is LOW when VLBI is < 1.178 V. LBO is high impedance during
shutdown.
4
REF
1.190 V Reference Voltage Output, bypassing with 150 nF capacitor if this pin is not loaded, bypassing with 1.0 mF
if this pin is loaded up to 2.5 mA @ VOUT = 3.3 V.

BAT
Battery input connection for internal Ring−Killer.
6
GND Ground.
7
LX
N−Channel and P−Channel Power MOSFET Drain Connection.
8
OUT Power Output. OUT also provides bootstrapped power to the device.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
1. This device contains ESD protection and exceeds the following tests:
Human Body Model (HBM) "2.0 kV per JEDEC standard: JESD22−A114.
Machine Model (MM) "200 V per JEDEC standard: JESD22−A115.
2. The maximum package power dissipation limit must not be exceeded.
