DA9022

DA9021/22 System PMIC with high efficiency USB power manager General description The DA9021/22 family is a highly integrated PMIC subsystem with supply domains to support a wide range of application processors, associated peripherals, and user interface functions. Combining a switched-mode USB compatible charger, full power-path management, three bucks, five linear regulators and support for multiple sleep modes, the DA9021 offers an energy-optimised solution suitable for portable handheld, wireless and, infotainment applications. DA9021/22 comes in a 4 x 4 mm, 64-bump, WLCSP package making it ideal for space constrained applications. The high-efficiency Li-lon/Polymer switching charger supports precise current/voltage charging as well as pre-charge and USB modes without processor interaction. During charging, the die temperature is thermally regulated enabling high-capacity batteries to be rapidly charged at currents up to 1.26 A with minimum thermal impact to space-constrained PCBs....
