Automotive 11ch Safe SoC PMIC with Extremely Low Quiescent Current
Jump to Page Section:
Overview
Description
The RAA271005 is a general purpose Power Management IC (PMIC) suitable for R-Car SoC series. It contains five DC/DC switching regulators and six low-drop out linear regulators (LDO). DCDC5 switching regulator can be configured to work in buck mode, or can be configured as a boost.
The RAA271005 PMIC supports low power operation, where three of the switching regulators (Buck3–Buck5) have been optimized to consume low quiescent current.
RAA271005 supports up to ASIL D functional safety, and includes an independent reference for monitoring of the output voltages, dual internal temperature monitors, challenge response watchdog timer, SoC and MCU error pin monitors, reset generator, a dedicated safety-control state machine, and safety shutdown path. An integrated 12-bit ADC monitors all input rails, output rails, internal temperature, and includes additional inputs to monitor external analog sources.
RAA271005 is available in a 6 × 11 BGA package, with 0.65mm pitch. The device is offered as AECQ100 Grade 1 operation, supporting an ambient temperature range of -40°C to +125°C.
See also the RAA271041. This product works together with the RAA271005 to support RCAR-S4.
