Monolithic Power Systems MP2760 1-4 Cell 6A Buck-Boost Charger
I2C-Controlled, 6A Buck-Boost Charger with NVDC Power Path Management and USB OTG for 1-Cell to 4-Cell Series Battery Applications
The MP2760 is a USB PD compliant, buck-boost charger with narrow voltage DC (NVDC) power path management and USB On-the-Go (OTG), and is designed for applications with 1-cell to 4-cell series battery packs. The IC can accept a wide range of input voltages (VIN), with a maximum of 22V.
The device can supply up to 21V at the IN pin when source mode is enabled. When an input power supply is present, the MP2760 charges the battery with one of four phases: constant current (CC) trickle charge, CC pre-charge, CC fast charge, or constant voltage (CV) charge. Other charging features include charge termination and auto-recharge. The MP2760 offers input current limiting and a minimum VIN limit function to avoid overloading the input power source.
The MP2760 can be configured via the I2C to set the parameters (e.g. input current limit, VIN limit, and charging current) in both charging mode and OTG mode. The device can also provide the operation status through the output and fault registers. Full protection features include input over-voltage protection (OVP), battery OVP, system OVP, thermal shutdown, and a configurable timer to prevent prolonged charging of a dead battery.
The MP2760 is available in a TQFN-30 (4mmx5mm) package.
