Product DetailsThe 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 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.APPLICATIONS

Evaluation Kits (1)
The ADP5062 charger evaluation system is composed of the ADP5062CP-EVALZ and a USB-to-serial-input/output interface (USB-SDP-CABLEZ). All ADP5062CP-EVALZ functions and circuits are controlled via one I2C bus connector. The I2C bus interfaces with the ADP5062 directly, and the digital input/output signals are controlled through an on-board input/output expander circuit on the I2C bus. The ADP5062CP-EVALZ also features a 3.4 V regulator for VDDIO generation. The ADP5062CP-EVALZ contains jumpers and numerous test points for easy evaluation.
The ADP5062 Evaluation and Design Software contains the ADP5062 graphical user interface (GUI) 3.0 installer. Use the GUI in conjunction with the USB-SDP-CABLEZ.
Full details on the ADP5062 are provided in the ADP5062 data sheet, which must be consulted in conjunction with this user guide when using the ADP5062CP-EVALZ.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
