Description
I2C-Compatible Interface Serial Clock.
Charging Enable. When DIG_IO3 = low or high-Z, charging is disabled. When DIG_IO3 = high,
charging is enabled.2, 3
Set Input Current Limit. When DIG_IO2 = low or high-Z, the input limit is defined by DIG_IO1
setting. When DIG_IO2 = high, the input limit is 1500 mA.2, 3
Battery Voltage Sense Pin.
Set Input Current Limit. This pin sets the input current limit directly. When DIG_IO1 = low or
high-Z, the input limit is 100 mA. When DIG_IO1 = high, the input limit is 500 mA.2, 3
Power Connections to USB VBUS. These pins are high current inputs when in charging mode.
Linear Charger Supply Side Input to Internal Isolation FET/Battery Current Regulation FET. High
current input/output.
Battery Supply Side Input to Internal Isolation FET/Battery Current Regulation FET.
Open-Drain Output to Indicator LED.
System Enable. This pin is the battery OK flag/open-drain pull-down FET to enable the system
when the battery reaches the VWEAK level.
I2C-Compatible Interface Serial Data.
Battery Pack Thermistor Connection. If this pin is not used, connect a dummy 10 kΩ resistor from
THR to AGND.
Bypass Capacitor Input.
Analog Ground.
Exposed Pad. Connection of the exposed pad is not required. The exposed pad can be connected
to analog ground to improve heat dissipation from the package to the board.
1 I is input, O is output, I/O is input/output, G is ground, and GPIO is the factory programmable general-purpose input/output.
2 See the Digital Input and Output Options section for details.
3 The DIG_IOx setting defines the initial state of the ADP5063. If the parameter or the mode that is related to each DIG_IOx pin setting is changed (by programming an
equivalent I2C register bit or bits), the I2C register setting takes precedence over the DIG_IOx pin setting. VINx connection or disconnection resets control to the
DIG_IOx pin.
4 N/A = not applicable.
