Overview
Description
RAA271000 is a general-purpose power management integrated circuit (PMIC) suitable for the Renesas R-Car system-on-chip (SoC) series. RAA271000 contains five DC/DC buck regulators and two low-dropout linear regulators (LDO). Supporting up to ASIL C functional safety, the RAA271000 includes an independent reference for monitoring functions, dual internal temperature monitors, challenge-response watchdog timer, SoC error pin monitors, a reset generator, a dedicated safety-control state machine, and a safety shutdown path. An integrated 12-bit ADC monitors all input rails, output rails, and internal temperature, and includes additional inputs to monitor external analog sources.
