1 / 142 page  DA9021/22 System PMIC with high efficiency USB power manager Datasheet Revision 2.5 17-Feb-2017 CFR0011-120-00 Rev 5 1 of 142 © 2017 Dialog Semiconductor 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. Key features ■ Switched USB charger with power path management ■ Three buck converters with DVC, 0.5 V to 3.6 V, up to 800 mA ■ Five programmable LDOs, high PSRR, 1 % accuracy ■ 32 kHz RTC oscillator ■ An integrated 7-channel general purpose ADC ■ 9-bit GPIO bus for enhanced wakeup and peripheral control ■ HS2-wire and 4-wire control interfaces ■ Unique USB supply detection and charge current selection ■ 64 WLCSP 4x4 mm, 0.5 mm pitch package Applications ■ Personal media players ■ Smartphone handsets ■ Personal navigation devices ■ Consumer infotainment devices ■ IoT |
