描述
The RTKA271005DE0000BU evaluation board provides a quick and comprehensive method for evaluating the RAA271005. The RAA271005 is a versatile automotive power management IC (PMIC) that is designed for a range of applications, including vehicle computers, communication gateways, and domain servers. It integrates five high-efficiency DC/DC switching regulators and six LDO (lowdropout) regulators.
特性
- Five high-efficiency switching regulators (buck) and six low-dropout (LDO) regulators for flexible power delivery.
- Programmable power sequencing to control the startup and shutdown of various power domains, suitable for complex SoCs (like Renesas' R-Car).
- Dual internal temperature sensors, voltage monitoring with a 12-bit ADC, and a challenge-response watchdog timer to ensure robust system operation.
- Supports low power modes such as Suspend-to-RAM (S2R) and DDR backup, allowing for efficient energy use in standby scenarios.
- Operates over a broad input voltage range (from 2.7V to 5.5V), suitable for automotive environments.
- Supports both I2C and SPI interfaces for configuration, monitoring, and control, allowing integration with external microcontrollers.
- Integrated overvoltage, undervoltage, overcurrent, and thermal protection mechanisms.
- Specifically designed for automotive applications like vehicle gateways, domain controllers, and infotainment systems, ensuring reliable operation under automotive conditions.
