1A, Single-Input, Single Cell Li-Ion Battery Charger with 50-mA LDO, and External Power

Path Control

Check for Samples: bq25060

FEATURES

DESCRIPTION

•

30V input Rating, With 10.5V Over-Voltage

Protection (OVP)

The bq25060 is a highly integrated Li-Ion linear

battery charger targeted at space-limited portable

applications. It operates from either a USB port or AC

Adapter and charges a single-cell Li-Ion battery with

up to 1A of charge current. The 30V input voltage

range with input over-voltage protections supports

low-cost unregulated adapters.

•

FET Controller for External Battery FET for

External Power Path Control (BGATE)

•

Input Voltage Dynamic Power Management

50mA integrated Low Dropout Linear

Regulator (LDO)

•

Programmable Charge Current Through ISET

and EN Pin

The bq25060 has a single power output that charges

the battery. The system load is connected to OUT.

The low-battery system startup circuitry maintains

OUT greater than 3.4V whenever an input source is

connected. This allows the system to start-up and run

whenever an input source is connected regardless of

the battery voltage. The charge current is

programmable up to 1A using the ISET input.

Additionally, a 4.9V 50mA LDO is integrated into the

IC for supplying low power external circuitry.

•

0.5% Battery Voltage Regulation Accuracy

7% Charge Current Regulation Accuracy

Thermal Regulation and Protection

Battery NTC Monitoring During Charge

Status Indication – Charging/Done

Available in small 2mm × 3mm 10 Pin SON

Package

The battery is charged in three phases: conditioning,

constant current and constant voltage. In all charge

phases, an internal control loop monitors the IC

junction temperature and reduces the charge current

if an internal temperature threshold is exceeded. The

charger power stage and charge current sense

functions are fully integrated. The charger function

has high accuracy current and voltage regulation

loops, charge status display, and charge termination.
