主要性能：耐高压30V（热插拔可达12V），BAT电压可达11V，带OVP,带DFN2*2-8封装。
GENERAL DESCRIPTION
The XC3105 Series is a complete constant
current & constant voltage linear charger for
single cell lithium-ion batteries. Its DFN package
and low external component counts make the
XC3105 Series ideally suited for portable
applications. Furthermore, the XC3105 Series is
specifically designed to work within USB power
specifications.
No external sense resistor is needed, and no
blocking diode is required due to the internal
MOSFET architecture. The charge voltage is fixed
at 4.2V/4.3V/4.35V/4.4V, and the charge current
can be programmed externally with a single
resistor. The XC3105 Series automatically
terminates the charge cycle when the charge
current drops to 1/10 the programmed value after
the final float voltage is reached.
When the input supply (wall adapter or USB
supply) is removed, the XC3105 Series
automatically enters a low current state, dropping
the battery drain current to less than 2uA. The
XC3105 Series can be put into shutdown mode,
reducing the supply current to 50uA.
Under-voltage lockout, automatic recharge and
two status pins to indicate charge and charge
termination.
