Description
Linear Charger Supply Side Input to the Internal Isolation FET/Battery Current Regulation FET.
High current input/output.
Power Connections to USB VBUS. These pins are high current inputs when in charging mode.
Analog Ground.
Battery Supply Side Input to Internal Isolation FET/Battery Current Regulation FET.
I2C-Compatible Interface Serial Clock.
I2C-Compatible Interface Serial Data.
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
Disable IC1. This pin sets the charger to the low current mode. When DIG_IO2 = low or high-Z, the
charger operates in normal mode. When DIG_IO2 = high, the LDO and the charger are disabled
and VINx current consumption is 280 µA (typical). 20 V VINx input protection is disabled and VINx
voltage level must be equal to or lower than 5.5 V.2, 3
Enable Charging. When DIG_IO3 = low or high-Z, charging is disabled. When DIG_IO3 = high,
charging is enabled.2, 3
Battery Pack Thermistor Connection. If this pin is not used, connect a dummy 10 kΩ resistor from THR
to GND.
Battery Voltage Sense Pin.
Open-Drain Output to Indicator LED.
System Enable. This is the battery OK flag/open-drain pull-down FET pin to enable the system
when the battery level reaches the VWEAK level.
Bypass Capacitor Input.
1 I is input, O is output, I/O is input/output, G is ground, and GPIO is factory programmable general-purpose input/output.
2 See the Digital Input and Output Options section for details.
3 DIG_IOx setting defines the initial state of the ADP5061. When the parameter or the mode that is related to each DIG_IOx pin setting is changed (by programming the
equivalent I2C register bit or bits), the I2C register setting dominates over the DIG_IOx pin setting. VINx connection or disconnection resets control to the DIG_IOx pin.
