SC806

Miniature High Current www.DataSheet4U.com Lithium-Ion Battery Charger POWER MANAGEMENT Description The SC806 is a fully integrated, single cell, constant-current (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 conjunction 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 monitor mode. If the battery voltage drops by 100mV from the CV voltage a new charge cycle will begin. rent source or as a current source for charging NickelCadmium (NiCd) and Nickel-Metal-Hydride (NiMH) batteries.
