Preliminary

EUP8084

Complete Linear Battery Charger with

Integrated Buck Converter and LDO

DESCRIPTION

FEATURES

The EUP8084 is

complete constant-current/

ꢀ

Battery Charger:

constant-voltage linear battery charger for a single-cell

4.2V lithium-ion battery with a 600mA step-down

converter, and a 300mA low dropout (LDO) linear

regulator. The input voltage range is 3.75V to 5.5V for the

battery charger and 2.6V to 5.5V for the step-down

converter and linear regulator, making it ideal for

applications operating with single-cell lithium-ion/polymer

batteries.

- Input Voltage Range : 3.75 V to 5.5V

- Constant-Current/Constant-Voltage Operation

with Thermal Feedback to Maximize Charge

Rate Without Risk of Overheating

- Internal 4.5 Hour Safety Timer for Termination

- Charge Current Programmable Up to 500mA

with 5% Accuracy

- C/10 Charge Current Detection Output

- 5ꢀA Supply Current in Shutdown Mode

The battery charger offers an integrated pass device,

reverse blocking protection, high accuracy current and

voltage regulation, charge status, and charge termination.

The charging current is programmable via external resistor

from 15mA to 500mA. In addition to these standard

features, the device offers current limit, thermal protection,

and soft-start.

ꢀ

Synchronous Buck Converter:

- Input Voltage Range: 2.6V to 5.5V

- Output Voltage Range: 0.6V to V_IN

- 600mA Output Current

- Up to 90% Efficiency

- 36ꢀA Quiescent Current

- 1.5MHz Switching Frequency

- 120ꢀs Start-Up Time

The step-down converter is a highly integrated converter

operating at a 1.5MHz switching frequency, minimizing

the size of external components while keeping switching

losses low. It has independent input and enable pins. The

output voltage ranges from 0.6V to the input voltage.

ꢀ

Linear Regulator:

- 300mA Output Current

- Low Dropout: 150mV at 300mA

- Fast Line and Load Transient Response

- High Accuracy: ± 1.5%

- 84ꢀA Quiescent Current

The EUP8084 linear regulator is designed for fast transient

response and good power supply ripple rejection.

Designed for 300mA of load current, it includes

short-circuit protection and thermal shutdown.

Short-Circuit, Over-Temperature, and Current

Limit Protection

The EUP8084 is available in a 16-lead 3mm×4mm TDFN

package and is rated over the -40°C to 85°C temperature

range.
