3A System PMIC with Switching USB Charger (3 bucks + 5 LDO)

The DA9021 features supply domains to support a wide range of application processors, associated peripherals and user interface functions. Combined with a single input USB compatible charger 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 processor interaction. During charging the die temperature is thermally regulated, enabling higher capacity batteries to be rapidly charges at current up to 1.26A with minimum thermal impact to space constrained PCB"s.
