Flexible system PMIC with high-efficiency USB power

manager

DA9052 is a quad buck PMIC with supply domain flexibility 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-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. 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 flow between an

AC adaptor, USB cable, and battery while maintaining USB power specification 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 configured to meet the start-up sequence, voltage, and timing requirements

for most applications. The power manager includes supply-rail qualification and system reset

management. For optimal processor energy-per-task performance, Dynamic Voltage Scaling (DVS),

is available on up to five supply domains. Dialog’s 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.
