flexible system pmic with high-effciency usb power manager DA9052 is a quad buck pmic with supply domain fexibility to support a wide range of application processors, associated peripherals, and user interface functions. combining a dual input switched-mode usb compatible charger, full power-path management, four bucks, ten linear regulators, and support for multiple sleep modes: the DA9052 offers an energy-optimised solution suitable for portable handheld, wireless, industrial, and infotainment applications. the high-effciency 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. usb suspend mode operation is supported and, for robustness, the power inputs are protected against over-voltage conditions. the autonomous power-path controller seamlessly detects and manages energy fow between an ac adaptor, usb cable, and battery while maintaining usb power specifcation compliance. the internally-generated system power rail supports power scenarios such as instant-on with a fully discharged battery. a reverse-protected backup battery charger is also integrated into the power- path function. controlled by a programmable digital power manager, the 14 user-programmable switched/linear regulators can be confgured to meet the start-up sequence, voltage, and timing requirements for most applications. the power manager includes supply-rail qualifcation and system reset management. for optimal processor energy-per-task performance, dynamic v oltage scaling (dvs), is available on up to fve supply domains. dialogs patented smartmirror? dynamic biasing is implemented on all linear regulators. an integrated 10-channel general purpose adc includes support for a touch screen controller with pen down detect, programmable high/low thresholds, an integrated current source for resistive measurements, and system voltage monitoring with a programmable low voltage warning. the adc has 8-bit resolution in auto mode and 10-bit resolution in manual conversion mode.
