uP8001A/B

Li-ion/Li Polymer Battery Charger

in VDFN and VQFN Packages

Features

General Description

The uP8001 is a highly integrated single-cell Li-ion or Li-

Polymer battery charger specifically designed to work with

AC adaptor or USB port.

Complete Charger for 1-Cell Li-ion Batteries

Integrated Pass Element and Current Sensor

No External Blocking Diode Required

1% Voltage Accuracy

The uP8001 charges battery with a minimum current when

the battery voltage is lower than 2.8V. The charger works

at constant current mode when the battery voltage is

between 2.8V and 4.2V, the charge current is

programmable up to 2Aby an external resistor. The charge

works at constant voltage mode when the battery voltage

is 4.2V. When the input voltage is removed, the uP8001

automatically enters a low quiescent current sleep mode,

dropping the battery drain current to 1uA.

Programmable Charge Current up to 2A

Programmable End-of Charge Current

NTC Interface for Battery Temperature Sensing

Battery Insertion Detection

1uA Battery Drain Current when Input Voltage

is Removed

Automatic Trickle Charging of Low Voltage

Cells

Other features include thermal foldback charge current,NTC

thermistor interface and automatic recharge. The uP8001

is available in thermal-enhanced and space-saving VQFN

and VDFNpackages.

Automatic Battery Recharge

RoHS Compliant and 100% Lead (Pb)-Free
