GENERAL DESCRIPTION
SL1053 charges the battery in three modes, precharge, constant current, constant voltage. After precharge, the SL1053 applies a constant current to the battery. An external sense-resister sets the charge current. The constant voltage mode continues until the battery reaches the regulation The battery temperature is continuously measured by an external thermistor through the TS pin. SL1053 inhibits charge until the temperature is within the range defined by users. FEATURES
