描述
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.

- 应用说明英语PDF 144 KB 2021年2月12日AI 生成的摘要: 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.
- 应用说明英语PDF 267 KB 2021年2月12日AI 生成的摘要: 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.
- 应用说明英语PDF 2.48 MB 2021年2月12日AI 生成的摘要: 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.
- 应用说明英语PDF 229 KB 2020年4月14日AI 生成的摘要: 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.

It explains regulator configurations, thermal design, and parameter measurements. The guide offers practical application information such as PCB layout recommendations, regulator usage, and configuration via GUI software. It supports system developers in optimizing device settings for single- and dual-core systems and provides insights into fault handling, sequencing, and power transitions. The document also includes references and definitions to assist in comprehensive system design.
- 应用说明英语PDF 149 KB 2020年4月14日AI 生成的摘要: The document explains the behavior of DA906x power management ICs when tested with a slowly ramping supply voltage. It details how the device monitors VSYS voltage changes, including the generation of VDD_WARN and VDD_FAULT events during slow voltage ramps. The document highlights that during slow rising voltage, the device may repeatedly attempt to power up and shut down due to threshold checks. A workaround involves setting the M_VDD_WARN mask bit to allow proper testing until the system fully powers up. The note also compares normal and slow ramp scenarios with timing diagrams to clarify device responses.
