Flexible System PMIC with High Efficiency USB Power Manager

A team of engineers is ready to answer your questions

An energy-optimized solution

The DA9052 is a highly integrated PMIC subsystem with supply domain flexibility to support a wide range of application processors, associated peripherals and user interface functions. Combined with a switched-mode DC input/USB compatible charger, full power path management and multiple sleep modes the device offers an energy-optimized solution suitable for portable handheld, wireless and infotainment applications.

Interfacing directly to a Li-Ion/Polymer battery pack, the high efficiency switching charger supports precise current/voltage charging as well as precharge and USB modes without processor interaction. During charging the die temperature is thermally regulated, enabling higher capacity batteries to be rapidly charges at currents up to 1.25A with minimum thermal impact to space constrained PCBs.
