GENERAL DESCRIPTION

scenario, which allows for immediate system function on connec-

tion to a USB power supply.

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.

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 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 dis-

connect or connect scenarios.

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.

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
