DA9053
Flexible High-Power System PMIC with 1.8 A
Switching USB Power Manager
General Description
The DA9053 is a quad buck 1 A per channel PMIC subsystem 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 DA9053 offers an energy-
optimized 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 1.8 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 powerpath
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 and 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.
