Kit Overview

The Analog Devices ADP5062CP-EVALZADP5062CP-EVALZ evaluation board provides an easy way to evaluate the ADP5062ADP5062 device. The ADP5062ADP5062 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 ADP5062ADP5062 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 ADP5062ADP5062 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.

Key Applications: Digital Still Cameras, Digital Video Cameras, Single Cell Li-Ion Portable Equipment, PDAs, Audio and GPS Devices, Portable Medical Devices, Mobile Phones.
