PMIC with Integrated Charger and
Smart Power Selector for Handheld Devices
General Description
The MAX8671X integrated power-management IC
(PMIC) is ideal for use in portable media players and
other handheld devices. In addition to five regulated
output voltages, the MAX8671X integrates a 1-cell lithi-
um ion (Li+) or lithium polymer (Li-Poly) charger and
Smart Power Selector? with dual (AC-to-DC adapter
and USB) power inputs. The dual-input Smart Power
Selector supports end products with dual or single
power connectors. All power switches for charging and
switching the system load between battery and external
power are included on-chip. No external MOSFETs are
required.
Maxim’s Smart Power Selector makes the best use of
limited USB or AC-to-DC adapter power. Battery
charge current and input current limit are independent-
ly set. Input power not used by the system charges the
