Li-Ion linear battery charger with LDO

Datasheet

production data

Applications

• Portable MP3 players

• Portable low-power devices

• Fitness portable devices

Description

The STNS01 is a linear charger for single-cell Li-

Ion batteries integrating an LDO regulator and

several battery protection functions.

DFN12L (3 x 3 mm²)

The device uses a CC/CV algorithm to charge the

battery. The fast-charge current can be

programmed using an external resistor. Pre-

charge current and termination current are scaled

accordingly. The floating voltage value is 4.2 V.

Features

• Charges single-cell Li-Ion batteries with CC-CV

The input supply voltage is normally used to

charge the battery and provide power to the LDO

regulator. When a valid input voltage is not

present and the battery is not empty, the device

automatically switches to battery power.

algorithm and charge termination

• Charge current programmable up to 200 mA

• 1% accuracy on floating voltage (4.2 V)

• Integrated 3.1 V LDO regulator

• Automatic power path management

• Battery overcharge protection

• Battery overdischarge protection

• Battery overcurrent protection

• Charging timeout

The STNS01 integrates overcharge,

overdischarge and overcurrent protection circuitry

to prevent the battery from being damaged under

fault conditions. It also features a charger enable

input to stop the charging process when battery

overtemperature is detected by external circuitry.

When the shutdown mode is activated, the battery

power consumption is reduced to less than

500 nA to maximize battery life during shelf time

or shipping.The device is available in a 3 × 3 mm²

12-lead DFN package.

• Very low battery leakage in

overdischarge/shutdown mode

• Low quiescent current

• Charge/fault status output

• Charger enable input

• Available in a 12-lead (3 x 3 mm²) DFN

package
