Charge current is set through the I²C interface — no external resistor needed for the current setpoint. The charger integrates over-temperature and over-voltage fault protection, and includes a programmable timer for charge termination.
Yes. The maximum battery pack voltage is 4.44 V, which covers the standard 4.2 V Li-ion termination voltage with margin.
The charge current is set via the I²C interface using the device's internal registers. No external programming resistor is required.
