Note 1: LX1 has internal clamp diodes to PGND1 and OUT1. LX2 has internal clamp diodes to PGND2 and OUT2. Applications
that forward bias these diodes should take care not to exceed the IC package power dissipation limit.
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.
PACKAGE THERMAL CHARACTERISTICS (Note 2)
WLP
Junction-to-Ambient Thermal Resistance ( q JA ) ..........41°C/W
Note 2: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-lay-
er board. For detailed information on package thermal considerations, refer to www.maximintegrated.com/thermal-tutorial .
ELECTRICAL CHARACTERISTICS (Note 3)
(V BATT = 3.7V, V CHG_IN = 5.0V, circuit of Figure 1, T A = -40 N C to +85 N C, unless otherwise noted. Typical values are at T A = +25 N C.)
