*Patent Pending
The SC805 is a fully integrated, single cell, constant-cur-
rent (CC)/constant-voltage (CV) Lithium-Ion battery
charger in a tiny 3x3 mm thermally enhanced lead free
MLP package. The SC805 can operate as a stand-alone
charger or in conjunction with a Power Management Con-
troller (PMIC).
The SC805 has a pre-charge function for trickle charging
deeply discharged batteries. The fast charge current is
enabled automatically when the battery voltage reaches
the required threshold. When the battery reaches the
constant voltage or CV portion of the charge curve the
SC805 switches to CV regulation mode. In this mode
the output current decays as the battery charges until
the termination current is reached and the SC805 sig-
nals the charge cycle is complete. The SC805 can be
configured to continue charging for a predetermined time
before turning off, or to turn off immediately upon termi-
nation. After turning off its output, The SC805 enters
monitor mode. If the battery voltage drops by 100mV
from the CV voltage a new charge cycle will begin. The
timer function also protects against charging faulty bat-
teries by turning off if the pre-charge time exceeds 1/4
of the total programmed charge duration.
The SC805 also provides battery detection, and a bat-
tery NTC thermistor interface to disable charging when
the battery temperature exceeds safe-to-charge limits.
The SC805 can also function as a general purpose cur-
rent source or as a current source for charging nickel-
cadmium (NiCd) and nickel-metal-hydride (NiMH) batter-
ies.
