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.
