Description

DA9062-A is a PMIC optimized for supplying systems with single- and dual-core processors, I/O, DDR memory, and peripherals. The target application range covers entry-level automotive In-Vehicle Infotainment (IVI) systems and FPGA-based applications including navigation and automotive telemetrics.

DA9062-A features four buck converters providing a total current of 8.5A. High efficiency is achieved over a wide load range by automatically selecting Pulse Frequency Modulation (PFM) or Pulse Width Modulation (PWM) modes. All power switches are integrated, removing the need for external Schottky diodes. A high switching frequency allows low-profile inductors to be used. Buck1 and Buck2 can be used in a 5A dual-phase configuration and Buck4 can be used as a DDR VTT supply. Four LDO regulators with programmable output voltage are integrated and provide up to 300mA each. DA9062-A is available in automotive AEC-Q100 Grade 2.

  1. Application Note
    Dialog PMICs and Terrestrial Cosmic Rays AN-PM-117
    PDF 144 KB Feb 12, 2021
    AI-generated Summary: Dialog Semiconductor mitigates single event transient (SET) risks caused by terrestrial cosmic rays in system PMICs and sub-PMICs by using design techniques such as redundancy in OTP memory cells and robust CMOS register architectures. The DA9063L-A device, built on a 250 nm CMOS process, demonstrates an extremely low soft error rate (SER) due to cosmic radiation, with failure rates far below other reliability concerns. Testing confirms no significant data corruption from electromagnetic interference (EMI) or electrostatic discharge (ESD). Overall, cosmic ray-induced soft errors contribute negligibly to device failure, ensuring high reliability in consumer and automotive applications.
  2. Application Note
    Shared IRQ Line Considerations AN-PM-059
    PDF 267 KB Feb 12, 2021
    AI-generated Summary: IRQ line-sharing among multiple devices in Linux-based systems can cause unhandled interrupts, leading to kernel failures. When an IRQ remains unserviced, the Linux kernel disables the IRQ line, potentially affecting all devices sharing it. This behavior arises after a threshold of unhandled interrupts triggers a diagnostic message and disables the IRQ. Solutions include allocating dedicated IRQs, masking interrupts via OTP or bootloader, and managing driver installation order. Specific recommendations for PMIC devices like DA9210 and DA9063 address interrupt masks and fault log clearance to mitigate such issues.

    PCB Layout Guidelines for Dialog PMICs AN-PM-010
    PDF 2.48 MB Feb 12, 2021
    AI-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.

    DA9062 Atlas7 Power Connections AN-PM-083
    PDF 229 KB Apr 14, 2020
    AI-generated Summary: The document details the integration and power connection scheme between the DA9062 PMIC and Qualcomm Atlas7 SoC, focusing on power sequencing, GPIO mappings, and timing diagrams for various system states such as cold boot, warm boot, power-down, watchdog timeout, and temperature warnings. It explains the use of GPIO signals for controlling power rails and system resets, including watchdog kick and reboot functions. The document also covers software driver support and development tools for configuring the PMIC. Key elements include power rail current ratings, signal roles, and timing requirements essential for stable system operation.

    Atmel SAMA5D3 Power Management with DA9061/2 AN-PM-067
    PDF 270 KB Apr 14, 2020
    AI-generated Summary: The DA9061 and DA9062 manage power for the SAMA5D3 microprocessor series by providing efficient, low-power operation with integrated safety features such as temperature and voltage supervision. They support flexible power rail sequencing and use high-frequency buck converters to enable compact designs. The power supply requirements and sequencing for the SAMA5D3 are detailed, including regulator mappings and signal interconnections based on the SAMA5D3 Xplained Evaluation Kit. The DA9062 offers additional features like an extra buck converter, dual-phase buck capability, DDR VTT supply, real-time clock, and coin cell charger. Evaluation results and configuration guidelines ensure reliable MPU operation.

  1. DA9062-00 vs DA9062-A0

    Hi, in AN-PM-080 it says in the revision log "Replaced DA9062-00 with DA9062-A0". Is this -A0 the correct (new) part number? The quotation we got from our distributor reads -00. Can anybody bring some light into this? Thanks, Thomas

  2. DA9062 Absolute Maximum VSYS Input Voltage

    I'm curious why the Absolute Maximum Rating for VSYS is the same as the Recommended Operating Conditions maximum. Shouldn't the Absolute Maximum Rating be a little bit higher than the Recommended maximum (5.5V)? I'm not in control over the voltage supplied to my product. Someone could ...
