The CXLB7388X series are highly integrated single cell
Li-Ion/Polymer battery charger IC designed for handheld
devices. The CXLB7388X accepts two power inputs,
normally one from a USB port and another one from
AC-adaptor. The CXLB7388X automatically selects the
USB-Port or the AC-adapter as the power source for the
system. In the USB configuration, the host can select from
the two preset charge rates of 100 mA and 500 mA. In the
AC−adapter configuration an external resistor sets the
magnitude of the charge current, which may be
programmed up to 1A.
The CXLB7388X charges the battery in three phases:
conditioning, constant current, and constant voltage.
Charge is terminated based on minimum current. An
internal charge timer provides a backup safety for charge
termination. The CXLB7388X automatically re-starts the
charge if the battery voltage falls below an internal
threshold. The CXLB7388X also automatically enters sleep
mode when both supplies are removed. No external sense
resistor or blocking diode is required for charging.
The CXLB7388X integrates internal power FET , current
sensor, charge status and reverse current protection in a
single monolithic devices.
