1 pcs : BQ25792RQMR - Battery Management I2C controlled, 5-A, 1-4 cell buck-boost charger with dual-input selector and USB PD 3.

BQ25792 Switch-Mode Buck-Boost Chargers Texas Instruments BQ25792 Switch-Mode Buck-Boost Chargers are fully integrated switch-mode buck-boost chargers for 1 cell to 4 cell Li-ion batteries and Li-polymer batteries. For a compact design and minimum components count, the charger integrates the 4 switching MOSFETs (Q1, Q2, Q3, Q4), input and charging current sensing circuits, the battery FET (BATFET), and all the loop compensation of the buck-boost converter. It provides high power density and design flexibility to charge batteries across the full input voltage range for USB Type-C™ and USB-PD applications such as smartphones, tablets, and other portable devices.
