Data Sheet
THEORY OF OPERATION
INTRODUCTION
The
cell lithium-ion or lithium-polymer batteries suitable for a
wide range of portable applications.
The highly efficient switcher dc-to-dc architecture enables
higher charging currents as well as a lower temperature
charging operation that results in faster charging times
because of the following features:
•
•
•
The
5.5 V but is tolerant of voltages of up to 12 V. This alleviates
the concern about USB bus spiking during disconnection or
connection scenarios.
The
charger output and the battery. This permits battery isolation
and, hence, system powering in a dead battery or no battery
scenario, which allows for immediate system function on
connection to a USB power supply.
The

Based on the type of USB source, which is detected by an
external USB detection device, the
apply the correct current limit for optimal charging and USB
compliance. The USB charger permits correct operation under
all USB compliant sources such as, wall chargers, host chargers,
hub chargers, and standard hosts and hubs.
A processor is able to control the USB charger using the I
to program the charging current and numerous other para-
