Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.

ELECTRICAL CHARACTERISTICS
(Typical Operating Circuit, VIN = 3.7V, CBATT = CIN1 = CIN2 = 2.2FF, CREFBP = 0.1FF, TA = -40NC to +85NC, unless otherwise noted.
Typical values are at TA = +25NC.) (Notes 3, 4)
ABSOLUTE MAXIMUM RATINGS
Note 1: LX has internal clap diodes to PGND and IN1. Applications that forward bias these diodes should take care not to exceed
the IC’s package-dissipation limits.
Note 2: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-
