BD71815AGW - Documentation

BD71815AGW is a single-chip power management IC for battery-powered portable devices. The IC integrates 5 buck converters, 8 LDOs, a boost driver for LED, and a 500mA single-cell linear charger. Also included is a Coulomb counter, a real-time clock (RTC), a 32 kHz crystal oscillator and a general-purpose output (GPO).
The IC’s buck converters supply power to the application processor as well as system peripherals such as DDR memory, wireless modules, and touch controllers. These regulators maintain high efficiency over a wide range of current loads by supporting both PFM and PWM modes. They also operate at a high switching frequency of 6MHz, which allows the use of smaller and cheaper inductors and capacitors. The regulator supplying the processor core also supports Dynamic Voltage Scaling (DVS).

White Paper

ISO 26262: Functional Safety Standard for Modern Road Vehicles
 
In this paper, as interest in functional safety and ISO 26262 grows and initiatives and responses are needed, we will introduce these concepts from a semiconductor manufacturer’s perspective, including how they affect the automotive sector.

Application Note

Platfrom Design Guide
 
The “BD71815AGWP latform Design Guide” provides design guideline which is recommended to PCB layer stack up, the components placement and the PCB routing. To reduce the risk that comes from PCB layout or parts placement, the guideline is strongly recommended to be adapted to the PCB design.
