MP2651GVT-0000-P is a buck-boost charger IC designed for battery packs with 1 cell to 4 cells in series. The device can accept a wide 4V to 22V input voltage (VIN) range to charge the battery. The buck-boost topology allows the battery voltage to be above or below VIN. When the input is present, the MP2651 operates in charge mode. It measures the battery voltage and charges the battery with four phases: constant current trickle charge, constant current pre-charge, constant current fast charge, and constant voltage charge. Other features include charge termination and autorecharge. The MP2651 also integrates the input current(IIN) limit and VIN limit to avoid overloading the input power source. This is compliant with the USB and PD specifications. The MP2651 can also supply a wide voltage range (3V to 21V) at the input when source mode is enabled. The device also has an output current (IOUT) limit with high resolution in source mode.
