DA9021/22
System PMIC with high efficiency USB power manager
General description
The DA9021/22 family is a highly integrated PMIC subsystem with supply domains to support a wide
range of application processors, associated peripherals, and user interface functions. Combining a
switched-mode USB compatible charger, full power-path management, three bucks, five linear
regulators and support for multiple sleep modes, the DA9021 offers an energy-optimised solution
suitable for portable handheld, wireless and, infotainment applications.
DA9021/22 comes in a 4 x 4 mm, 64-bump, WLCSP package making it ideal for space constrained
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 to space-constrained PCBs.
DA9021 offers a merged buck configuration for a combined 1.6 A or DA9022 offers a higher voltage
capability on one DC-DC buck converter which is ideal for peripherals and memory running up to
3.6 V. USB suspend mode operation is supported and, for robustness, the power input is protected
against over-voltage conditions.
The internally generated system power rail supports power scenarios such as instant-on with a fully
discharged battery.
The power efficiency and flexibility of the switching DC-DC bucks is maintained to generate the
various supply domains.
Controlled by a programmable digital power manager, the eight user-programmable switched/linear
regulators may 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 four supply domains. Dialog’s patented SmartMirror™ dynamic biasing is
implemented on all linear regulators.
