Power-Management ICs for
Single-Cell, Li+ Battery-Operated Devices
General Description
The MAX8662/MAX8663 power-management ICs
(PMICs) are efficient, compact devices suitable for
smart cellular phones, PDAs, Internet appliances, and
other portable devices. They integrate two synchronous
buck regulators, a boost regulator driving two to seven
white LEDs, four low-dropout linear regulators (LDOs),
and a linear charger for a single-cell Li-ion (Li+) battery.
Maxim’s Smart Power Selector? (SPS) safely distrib-
utes power between an external power source (AC
adapter, auto adapter, or USB source), battery, and the
system load. When system load peaks exceed the
external source capability, the battery supplies supple-
mental current. When system load requirements are
small, residual power from the external power source
charges the battery. A thermal-limiting circuit limits bat-
tery-charge rate and external power-source current to
prevent overheating. The PMIC also allows the system
