Features

2.6 mm x 2 mm WLCSP Package
Fully programmable via I²C
Flexible digital control inputs
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 -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 30 mΩ battery isolation FET between battery and charger output
Thermal regulation prevents over heating
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 minimum required level for guaranteed system start-up.

Additional Details

The ADP5061 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 USB host port.

The ADP5061 operates from a 4 V to 6.7 V input voltage range but is tolerant of voltages up to 20 V. The 20 V voltage tolerance alleviates the concerns about the USB bus spiking during disconnect or connect scenarios.

The ADP5061 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 connection to a USB power supply.

Based on the type of USB source, which is detected by an external USB detection chip, the ADP5061 can be set to apply the correct current limit for optimal charging and USB compliance.

The ADP5061 has three factory programmable digital input/output 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.

Product Detail

The ADP5061 charger evaluation system is composed of an evaluation board, an USB A-to-USB Micro B cable, and an USB A adapter board. All evaluation board functions and circuits are controlled via one I²C bus connector. The I²C bus interfaces with the ADP5061 directly, and the digital input/output signals are controlled through an on-board input/output expander circuit on the I²C bus. The evaluation board also features a 3.4 V regulator for VDDIO generation. The board contains jumpers and numerous test points for easy evaluation.

The ADP5061CB-EVALZ evaluation kit contains a CD with the ADP5061 graphical user interface (GUI) Version 3.0 installer. Use the GUI in conjunction with the USB-SDP-CABLEZ USB to serial I/O interface.

Full performance details are provided in the ADP5061 data sheet, and the ADP5061 data sheet should be consulted in conjunction with this user guide.
