The MP2762A from Monolithic Power Systems is a Buck/Boost Charger IC that is ideal for smartphones with two cells in series, bluetooth speakers, and portable gimbals. It is a highly integrated charger IC with narrow voltage DC (NVDC) power path management and USB on-the-go (OTG) for battery packs with two cells in series. This IC can accept a wide range of input voltages for charging, with a maximum of 21 V. It has two operating modes during the charging process, the boost charging mode when the input voltage is below 5.75 V, and the buck charging mode when the input voltage exceeds 8.5 V. This IC has a configurable input voltage limit ranging up to 6 A and a configurable charge current ranging up to 6A. It benefits from various safety features that include input over-voltage protection (OVP), battery OVP, system OVP, thermal shutdown, battery temperature protection, and a configured timer to prevent prolonged charging of a dead battery. This RoHS-compliant IC can be configured to set the parameters in both charging mode and OTG mode with the aid of an I2C interface. It is available in a surface-mount package that measures 4 x 5 mm.
