RAA271000 General-Purpose Power Management IC for Automotive Applications Datasheet
●RAA271000 contains five high efficiency DC/DC synchronous buck regulators and two low-dropout linear regulators (LDO).
●RAA271000 can support ASIL D system safety goals. It includes independent reference for monitoring of the output voltages, dual internal temperature monitors, challenge-response watchdog timer, SoC error pin monitors, reset generator, a dedicated safety-control state machine, and a 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.
●RAA271000 is available in a 5.71×8.46, 0.8mm pitch, BGA package. The device is offered as AEC-Q100 Grade 1 operation supporting an ambient temperature range of -40°C to 125°C.
