High Efciency Battery
Charger/USB Power Manager
The LTC4088 is a high efciency USB PowerPathTM
controller and Li-Ion/Polymer battery charger. It includes
a synchronous switching input regulator, a full-featured
battery charger and an ideal diode. Designed specically for
USB applications, the LTC4088’s switching regulator auto-
matically limits its input current to either 100mA, 500mA
or 1A for wall-powered applications via logic control.
The switching input stage provides power to VOUT where
power sharing between the application circuit and the
battery charger is managed. Unlike linear PowerPath
controllers, the LTC4088’s switching input stage can use
nearly all of the 0.5W or 2.5W available from the USB port
with minimal power dissipation. This feature allows the
LTC4088 to provide more power to the application and
eases thermal issues in space-constrained applications.
An ideal diode ensures that system power is available
from the battery when the input current limit is reached
or if the USB or wall supply is removed.
The LTC4088 is available in the low prole 14-Lead 4mm
× 3mm × 0.75mm DFN surface mount package.
