Linear Li-Ion Battery Charger with Power

Path and USB Compatibility in LFCSP

Data Sheet

ADP5062

FEATURES

GENERAL DESCRIPTION

4 mm × 4 mm LFCSP package

Fully programmable via I²C

Flexible digital control inputs

The ADP5062 charger is fully compliant with USB 3.0 and the

USB Battery Charging Specification 1.2 and enables charging

via the mini USB VBUS pin from a wall charger, car charger, or

Up to 2.1 A current from an ac charger in LDO mode

Operating input voltage from 4.0 V to 6.7 V

Tolerant input voltage from −0.5 V to +20 V (USB VBUS)

Fully compatible with USB 3.0 and USB Battery Charging

Specification 1.2

Built-in current sensing and limiting

As low as 54 mΩ battery isolation FET between battery and

charger output

Thermal regulation prevents overheating

Compliant with JEITA 1 and JEITA 2 Li-Ion battery charging

temperature specifications

SYS_EN flag permits the system to be disabled until battery is at

the minimum required level for guaranteed system start-up

USB host port.

The ADP5062 operates from a 4 V to 6.7 V input voltage range

but is tolerant of voltages up to 20 V thereby alleviating concerns

about USB bus spikes during disconnect or connect scenarios.

The ADP5062 features an internal FET between the linear

charger output and the battery. This permits battery isolation

and, hence, system powering under a dead battery or no battery

scenario, which allows for immediate system function on connec-

tion to a USB power supply.

Based on the type of USB source, which is detected by an external

USB detection chip, the ADP5062 can be set to apply the correct

current limit for optimal charging and USB compliance.

The ADP5062 has three factory-programmable digital input/out-

put pins that provide maximum flexibility for different systems.

These digital input/output pins permit combinations of features

such as, input current limits, charging enable and disable, charging

current limits, and a dedicated interrupt output pin.
