Integrated with the charger, the IC supports production test mode, which provides 4.2 V at up to 2.3 A to the system. To facilitate fast system startup, the IC includes a power path circuit, which disconnects the battery from the system rail, ensuring that the system can power up quickly following a VBUS connection. The power path circuit ensures that the system rail stays up when the charger is plugged in, even if the battery is dead or shorted. The charging parameters and operating modes are programmable through an I 2C Interface that operates up to 3.4 Mbps. The charger and boost regulator circuits switch at 3 MHz to minimize the size of external passive components. The FAN5404X provides battery charging in three phases: conditioning, constant current, and constant voltage. The integrated circuit automatically restarts the charge cycle when the battery falls below a voltage threshold. If the input source is removed, the IC enters a high-impedance mode blocking battery current from leaking to the input. Charge status is reported back to the host through the I 2C port. Dynamic input voltage control prevents a weak adapter ’s voltage from collapsing, ensuring charging capability from such adapters. The FAN5404X is available in a 25-bump, 0.4 mm pitch, WLCSP package.
