Description
The FAN54300 combines two highly integrated switch-mode
chargers and a boost regulator to minimize single-cell Li-Ion
charging time from a USB and/or auxiliary power source.
Charging parameters and operating modes are programmable
through an I2C Bus® interface that operates up to 3.4 Mbps.
The charger and boost regulator circuits switch at 3 MHz to
minimize the size of the external passive components.
The FAN54300 provides battery charging in three phases:
conditioning, constant current, and constant voltage.
To ensure USB compliance and minimize charging time, the
USB input current is limited to the value set through the I2C
host. Charge termination is determined by a programmable
minimum current level. A safety timer with reset control
provides a safety backup for the I2C host.
The IC automatically restarts the charge cycle when the
battery falls below an internal threshold. If the input source is
removed, the IC enters a high-impedance mode, with leakage
from the battery to the input prevented. Charge status is
reported back to the host through the I2C port. Charge current
is reduced when the die temperature reaches 120°C.
The FAN54300 can operate as a boost regulator on command
from the system. The boost regulator includes a soft-start that
limits inrush current from the battery.
The FAN54300 is available in a 30-bump, 0.4 mm pitch,
wafer-level, chip-scale package (WLCSP).
