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.

1 Undervoltage lockout generated normally from ISO_Sx or ISO_Bx; in certain transition cases, it can be generated from VINx.
2 These values are programmable via I2C. Values are given with default register values.
3 The output current during charging may be limited by the input current limit or by the isothermal charging mode.
4 During weak charging mode, the charger provides at least 20 mA of charging current via the trickle charge branch to the battery unless trickle charging is disabled.
Any residual current, which is not required by the system, is also used to charge the battery.
5 Either JEITA1 (default) or JEITA2 can be selected in I2C, or both JEITA functions can enabled or disabled in I2C.
