General Description
The DA9053 is a quad buck PMIC subsystem suitable for use on Freescale’s
Multimedia Reference Platforms.
Combining a powerful switched-mode DC input/USB compatible charger, full
power path management and multiple sleep modes the device oers an energy-
optimised solution suitable for portable handheld, wireless and infotainment
applications.
Interfacing directly to a Li-lon/Polymer battery pack the high eciency switching
charger supports precise current/voltage charging as well as pre charge and USB
modes without processor interaction. During charging the die temperature is ther-
mally regulated enabling higher capacity batteries to be rapidly charged at currents
up to 1.8A 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
ow between an AC adaptor, USB cable and battery whilst maintaining USB power
specication compliance.
The internally-generated system power rail supports power scenarios such as
instant-on with a full discharged battery. A reverse-protected backup battery char-
ger is also integrated into the power path function.
The power eciency and exibility 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 congured 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 ve supply domains. Dialog’s patented Smart Mirror™ dynamic
biasing is implemented on all linear regulators.
