DA9053 Block Diagram
Description
DA9053 is a quad buck PMIC subsystem with supply domain flexibility to support a wide range of multicore application processors including ARM multicore devices, associated peripherals and user interface functions.
Combined with a switched-mode DC input/USB compatible charger, full power path management and multiple sleep modes, the device offers an energy-optimized solution suitable for portable handheld, wireless and infotainment applications. Interfacing directly to a Li-Ion/Polymer battery pack, the high efficiency switching charger supports precise current/voltage charging as well as precharge and USB modes without processor interaction.

- Application NotePDF 2.48 MB Feb 12, 2021AI-generated Summary: Optimizing PCB layout is essential for reliable and high-performance integrated power management solutions. Key principles include maintaining low ground impedance through thick current-carrying traces, ground planes, and multiple vias. Sensitive signals must be shielded from noise, and power and ground planes should be placed under PMICs to minimize inductance. Specific layout guidelines address buck, boost converters, LDOs, and battery chargers. Examples from Dialog’s reference designs illustrate best practices. Design-in services are available to review schematics and layouts to enhance efficiency and reliability.
- Application NotePDF 597 KB Mar 31, 2020AI-generated Summary: The document details the power connectivity between the DA9053 PMIC and the NXP™ i.MX 6DualLite or Solo application processors, focusing on multimedia applications. It covers power domains, component selection, and interconnection based on the i.MX6 DualLite SABRE board. The DA9053 integrates multiple buck converters, LDOs, a dual input charger, LED boost converter, watchdog timer, ADCs, and touch screen interface to support flexible power management. It supports Dynamic Voltage Scaling (DVS) for efficient power savings and reduces system cost and size compared to discrete solutions. The document also includes power-up sequences, recommended external components, and driver support information. PCB design files typically bundled include BOM, schematics, and Gerber files.
- Application NotePDF 374 KB Mar 31, 2020AI-generated Summary: Suspend mode maintains essential power rails active to preserve system configuration, enabling quick wake-up without a full reboot. The system enters suspend via hardware signals or register commands, with specific regulators set to retention voltages. Resume triggers include key presses, hardware signals, charger connection, RTC alarms, or GPIO events. Configuring PMIC registers optimizes suspend and resume sequences, ensuring nRESET does not reset the processor during suspend and that voltage regulators maintain required levels. This approach supports efficient low-power standby states with rapid system recovery.

- Application NotePDF 639 KB Apr 18, 2018AI-generated Summary: The document details the design and operation of a high-efficiency autonomous battery charger featuring fully automatic charging without host intervention. It explains the charger’s architecture, including external MOSFET protection, a buck converter for power efficiency, and a linear charging stage with an active diode. It guides selecting external components based on electrical characteristics and outlines the three-phase charging process: pre-charge, constant current fast charge, and constant voltage top-off. The pre-charge phase safely initiates charging for deeply discharged batteries, with configurable current settings and LED indicators. The document supports designers in optimizing charger parameters for handheld applications.
- Application NotePDF 468 KB Apr 18, 2018AI-generated Summary: Initial I2C communication with the DA9053 2-wire interface can encounter issues such as NAK responses to the first message or the SDA line being held low, causing bus lock. These problems arise because the I2C module does not reset properly during power-up or shutdown, leading to invalid states. A software workaround involves toggling the SCL line nine times and manipulating SDA and SCL lines as GPIOs before enabling I2C control. This ensures the device returns to an idle state ready for communication. The workaround is typically implemented in the bootloader and can be applied to any I2C slave device.
- Application NotePDF 851 KB Apr 18, 2018AI-generated Summary: The DA905x Touch Screen Interface supports 4-wire resistive touch screens with pen pressure measurement capabilities. It offers user-programmable controls such as pre-charging, settling time delay, and configurable sample rates up to 3 kHz, making it suitable for battery-powered devices like PDAs, PMPs, and smartphones. The interface measures X and Y coordinates by applying voltage across conductive ITO layers and detects touch pressure by calculating resistance changes. It includes low power and active reading modes, configurable parameters like TSI_DELAY and TSI_SKIP, and guidelines for PCB layout to minimize noise and resistance effects. The document explains the theory of operation, configuration steps, and application examples.
- Application NotePDF 341 KB Oct 17, 2016AI-generated Summary: Charging a nearly full battery requires careful management of charger settings to avoid damaging the battery or reducing its lifespan. Key parameters include battery temperature, voltage, and charger voltage. The charging cycle starts only if the battery voltage is below a threshold defined by the charge termination voltage minus a configurable drop voltage (VCHG_DROP). Battery path resistance affects the actual voltage at the battery terminals, causing voltage drops during charging and discharging that can trigger unintended charge cycles. Optimizing VCHG_DROP settings, such as starting at 100 mV and increasing to 200 mV during charging, prevents continuous cycling and prolongs battery life. Understanding these factors helps ensure efficient and safe charging behavior.
