AL1265 is a special high-precision linear battery charger circuit design, ideal for those low-cost, portable charger. It combines high-precision pre-charge, constant current charging, constant voltage charging, the battery state detection, low leakage charging is completed, the charging status indication performance in one, can be widely used in the field of EPC, mobile multimedia handheld devices. AL1265 by detecting the battery voltage to determine the charging status: pre-charge, constant current charging, constant voltage charging. When the battery voltage is less than the threshold voltage of VMIN (typically, 6V), in the pre-charge state to a smaller current to charge the battery, the precharge current can be adjusted by an external resistor. Pre-charge after the battery voltage reaches VMIN, into the constant-current charging fast charging state, the charging current IREG can be adjusted by external resistor R1, the constant current charging the battery voltage rises to the constant voltage charging voltage VREG (typically 8.4V). Then enters a constant voltage charging state, the charging voltage accuracy of better than ± 1%, in this state, the charging current will gradually decrease, when the charging current is less than the threshold value ITERM, charging is completed. When charging is completed, will always monitor the battery voltage when the battery voltage is less than the threshold VRECHG (general VREG-250mV for) when the battery is recharged, the charge into the next cycle. AL1265 also can adjust the external resistor to mention the end of the battery voltage is adjustable saturation; high-end cell saturation voltage, the voltage can be set to the desired point.
