EUP8075
尔 USB-Compliant Li-Ion Battery Charger
Integrated with System Power-Path Management
DESCRIPTION
The EUP8075 series of devices are highly integrated
Li-ion linear chargers and system power path management
devices targeted at space-limited portable applications.
The devices operate from either a USB port or AC adapter.
The high input voltage range with input overvoltage
protection supports low-cost unregulated adapters.
The EUP8075 offer DC supply power-path management
with autonomous power-source selection, power FETs and
current sensors, high-accuracy current and voltage
regulation, charge status, and charge termination, in a
single monolithic device.
The EUP8075 power the system while independently
charging the battery. This feature reduces the charge and
discharge cycles on the battery, allows for proper charge
termination and allows the system to run with an absent or
defective battery pack. This feature also allows for the
system to instantaneously turn on from an external power
source in the case of a deeply discharged battery pack. The
IC design is focused on supplying continuous power to the
system when available from the AC adapter or battery
sources.
