Product brief DA9052
DA9052 Flexible system PMIC with high efficiency
USB power manager
General Description
The DA9052 is a highly integrated PMIC
subsystem with supply domain flexibility to
support a wide range of application processors,
associated peripherals and user interface
functions.
Combined with a switched-mode DC input/USB
compatible charger, full power path management
and multiple sleep modes the device offers an
energy-optimised solution suitable for portable
handheld, wireless and infotainment applications.
Interfacing directly to a Li-lon/Polymer battery pack
the high efficiency 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 higher capacity batteries
to be rapidly charged at currents up to 1.25A with
minimum thermal impact to space-constrained PCB’s.
USB suspend mode operation is supported and for
robustness the USB power inputs are internally
protected against over-voltage conditions.
The autonomous power path controller seamlessly
detects and manages energy flow between an AC
adaptor, USB cable and battery whilst maintaining
USB power specification compliance.
The internally-generated system power rail supports
power scenarios such as instant-on with a full
discharged battery. A reverse-protected backup
battery charger is also integrated into the power path
function.
The power efficiency and flexibility of the switching
input stage is maintained to the generated supplies.
Controlled by a programmable digital power manager
the 14 user- programmable switched/linear regulators
may be configured for a variety of start up sequences,
levels and timings.
For optimal processor energy-per-task performance
dynamic voltage scaling is permissible on up to five
supply domains. Dialog’s patented Smart Mirror ™
dynamic biasing is implemented on all linear
regulators.
Available in an 86LD UFNBA-QFN 7x7mm package
