FAN54040 – FAN54047 • Rev. 1.0.2
Description
The FAN5404X family includes I2C controlled 1.55 A USB-
compliant switch-mode chargers with power path operation
and USB OTG boost operation. 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 I2C 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 I2C port.
Dynamic input voltage control prevents a weak adapters
voltage from collapsing, ensuring charging capability from
such adapters.
The FAN5404X is available in a 25-bump, 0.4 mm pitch,
WLCSP package.
