9.3.14 Charge Current Programming by External Components (ISET)

The fast charge current is user programmable through an external resistor or through registers over I2C. Set the fast charge current by connecting a resistor from ISET to GND. If no ISET resistor is connected and the pin is tied to GND, the default ISET register value is used. While charging, if the charge current is using the externally programmed value, the voltage at ISET reflects the actual charging current and can be used to monitor charge current. The current out of ISET is 1/100 (±10%) of the charge current. The charge current can be calculated by using Table 5 for guidance:
