The SC806 is a fully integrated, single cell, constant-cur-
rent (cc)/constant-voltage (cv) Lithium-Ion battery charger
in a tiny 3x3 mm thermally enhanced MLP package. The
SC806 can operate as a stand-alone charger or in con-
junction with a Power Management Controller (PMIC).
The SC806 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
SC806 switches to CV regulation mode. In this mode
the output current decays until the termination current is
reached. At this point the SC806 signals the charge cycle
is complete and turns off the output and enters the moni-
tor mode. If the battery voltage drops by 100mV from
the CV voltage a new charge cycle will begin.
The SC806 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.
