MP2639B is a boost switching charger for single-cell Li-ion/Li-polymer batteries. It provides input voltage protection up to 16V and integrates a bi-directional switching charger with up to 5A charge capability in boost mode and 3A discharge capability in OTG buck mode. The device employs Low Rds(ON) power MOSFETs, which enable the highest charging and discharging efficiency for best-in-class thermal performance. Robust protections including programmable timer back-up protection, JEITA battery NTC monitor, thermal regulation, thermal shutdown, and short-circuit protection for Boost mode are available. The MP2639B is available in a small QFN-26 (4mmx4mm) package, designed for solutions such as portable e-ink printers, USB PD power bank applications for smart phones & tablets, wireless speakers, E-cigars, and digital cameras.
