MP2770 I2C-Controlled, 6A, 1-Cell Switching Charger with Power Path Management and 3.65A Boost Output DESCRIPTION The MP2770 is a highly-integrated, flexible, switch-mode battery management device with system power path management. It is designed for single-cell Li-ion and Li-polymer batteries used in a wide range of portable applications. The IC has an integrated IN to SYS passthrough path to send input voltage (VIN) to the system even while charging is disabled. When the input is present, the MP2770 operates in charge mode. The device detects the battery voltage (VBATT) automatically and charges the battery with three phases: precharge, constant current fast charge, and constant voltage charge.
