Monolithic Power Systems (MPS) MP2632B 3A Battery Charger

Monolithic Power Systems (MPS) MP2632B 3A Battery Charger is an all-in-one, highly integrated, flexible, switch-mode battery charger with system power-path management. The battery charger is designed for single-cell Li-ion or Li-polymer batteries. The MP2632B comes with an integrated V_IN to SYS pass-through path to pass the input voltage to the system with higher priority than the charging path. This charger operates in charge mode in the presence of input power and switches to boost mode in the absence of an input source. The MP2632B charger also incorporates an integrated 4-LED driver for voltage-based fuel gauge indication. Typical applications include sub-battery, power-banks for smartphones, tablets, and other portable devices.
