500mA/1.5A STANDALONE LINEAR LI-ION BATTERY CHARGE

DESCRIPTION

FEATURES

The A4061 is a single cell, fully integrated constant

current (CC)/constant voltage (CV) Li-ion battery

charger. Its compact package with minimum

external components requirement makes the A4061

ideal for portable applications.

No external sense resistor or blocking diode is

necessary for the A4061. Build-in thermal feedback

mechanism regulates the charge current to control

the die temperature during high power operation or

at elevated ambient temperature.

The A4061 has a pre-charge function for trickle

charging deeply discharged batteries. The fast

charge current can be programmed by an external

resistor. CV regulation mode is automatically

enabled once the battery’s charging curve reaches

the constant voltage portion. The output current then

decays and is finally terminated once the charge

current drops to 1/10^thof the programmed value.

The A4061 keeps monitoring the battery voltage and

enables a new charge cycle once the voltage drops

by 150mV below the CV value.



Standalone Capability with no Requirement

of External MOSFET, Sense Resistor or

Blocking Diode.

Complete Linear Charger in Compact Package

for Single Cell Lithium-Ion Batteries

Programmable Pre-charge, Fast Charge and

Termination Current.

Constant-Current/Constant-Voltage Operation

with Thermal Regulation to Maximize Charge

Rate Without Risk of Overheating

Charges Single Cell Li-Ion Batteries Directly

Soft-Start Limits Inrush Current

Available in SOT-26 and PSOP8 Packages

Power supply state is constantly monitored and the

battery drain current is reduced to minimum value

automatically when the A4061 senses a lack of input

power. In its shutdown mode, the A4061 can reduce

the supply current to less than 25μA. A status pin

outputs a logic HIGH/LOW to indicate the charging

status and the presence of power supply.

APPLICATION



Cellular Telephones, PDAs, MP3 Players

Charging Docks and Cradles

Bluetooth Applications

ORDERING INFORMATION
