www.DataSheet4U.com Fully Integrated High Current Lithium-Ion Battery Charger System POWER MANAGEMENT Description The SC803 is a fully integrated, single cell, constant-current constant-voltage Lithium-Ion battery charger management system. The SC803 has built in intelligence and extreme functionality. When the battery voltage is below 2.8V the charger operates in a pre-charge mode with a charging current of up to 125mA based on the ITERM pin resistor. This pre-charge mode is set to limit power dissipation due to an undercharged battery. When the battery voltage exceeds 2.8V, the charger enters a fast charge mode. In this mode, the SC803 delivers up to 1.5A to the battery based on the IPRGM pin resistor.
