DA9052
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.
