产品概述 返回TOP
The CXLB7387X series are highly integrated single cell
Li-Ion/Polymer battery charger IC designed for handheld
devices. The CXLB7387X integrates internal power FET,
current sensor, charge status and reverse current protection
in a single monolithic devices.When AC-adapter is applied,
an external resistor sets the magnitude of the charge
current, which may be programmed up to 1A.
The CXLB7387X 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 CXLB7387X automatically re-starts the
charge if the battery voltage falls below an internal
threshold. The CXLB7387X also automatically enters sleep
mode when DC supplies are removed. No external sense
resistor or blocking diode is required for charging.
