bq2510x 250-mA Single Cell Li-Ion Battery Chargers, 1-mA Termination, 75-nA Battery

Leakage

1 Features

3 Description

The bq2510x series of devices are highly integrated

Li-Ion and Li-Pol linear chargers targeted at space-

limited portable applications. The high input voltage

range with input overvoltage protection supports low-

cost unregulated adapters.

•

Charging

–

1% Charge Voltage Accuracy

10% Charge Current Accuracy

Supports Applications for Very Low Charge

Currents - 10 mA to 250 mA

The bq2510x has a single power output that charges

the battery. A system load can be placed in parallel

with the battery as long as the average system load

does not keep the battery from charging fully during

the 10 hour safety timer.

–

Supports minimum 1-mA Charge Termination

Current

Ultra Low Battery Output Leakage Current -

Maximum 75 nA

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.

Adjustable Termination and Precharge

Threshold

High voltage Chemistry Support: 4.35 V with

bq25100H/01H, 4.30 V with bq25100A

•

Protection

The charger power stage and charge current sense

functions are fully integrated. The charger function

has high accuracy current and voltage regulation

loops and charge termination. The pre-charge current

and termination current threshold are programmed

via an external resistor on the bq2510x. The fast

charge current value is also programmable via an

external resistor.
