MP2665AGQB-0000-P

MP2665AGQB-0000-P is a highly integrated, single-cell Li-ion/Li-polymer battery charger with system power path management. This battery takes input power from either an AC adapter or a USB port to supply the system load and charge the battery simultaneously. The charger features pre-charge, constant current (CC) fast charge, constant voltage (CV) regulation, charge termination and automatic recharge. This battery provides system short-circuit protection (SCP) by limiting the current from the input to the system, as well as the current from the battery to the system. This feature is especially critical to prevent the Li-ion battery from being damaged due to excessively high currents. An on-chip battery under-voltage lockout (UVLO) threshold cuts off the path between the battery and the system if the battery voltage drops below the configurable battery UVLO threshold. It is mainly used in wearable devices, smart handheld devices, fitness accessories and smartwatches.
