GENERAL DESCRIPTION
The ADP5061 charger is fully compliant with the USB 3.0 and
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 4V to 7.0V input voltage range
but is tolerant of voltages up to 20V. This alleviates the
concerns about the USB bus spiking during disconnect or
connect scenarios.
The ADP5061 also 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 3 fuse programmable digital input/output
pins providing maximum flexibility for different systems. These
programmable digital output / input pins permit combinations
of features such as, input current limits, charging enable-
disable, charging current limits and dedicated interrupt output
pin.
