The ADP5061ACBZ-4-R7 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 ADP5061ACBZ-4-R7 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 ADP5061ACBZ-4-R7 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 batteryscenario, 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 ADP5061ACBZ-4-R7 can be set to apply the correct current limit for optimal charging and USB compliance.
The ADP5061ACBZ-4-R7 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.
