Monolithic Power Systems (MPS) MP2770 Digital 6A 1-Cell Switching Chargers

Monolithic Power Systems (MPS) MP2770 Digital 6A 1-Cell Switching Chargers are flexible, switch-mode battery management devices with system power path management. In portable applications, the Monolithic Power Systems (MPS) MP2770 chargers are designed for single-cell Li-ion and Li-polymer batteries. The devices feature an integrated IN to SYS pass-through, allowing input voltage (VIN) to power the system even when charging is disabled. When input is present, the MP2770 charges the battery in three phases: pre-charge, constant current fast charge, and constant voltage charge. The devices also prioritize system power needs by managing input current limit (IIN_LIMIT) and VIN regulation.
