GENERAL DESCRIPTION
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.
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 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 ADP5061 can be set to apply the correct
current limit for optimal charging and USB compliance.
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.
