RAA271000

General-Purpose Power Management IC for Automotive Applications

The RAA271000 is a general-purpose Power

Management Integrated Circuit (PMIC) suitable for

the Renesas R-Car SoC series.

Features

▪ Input range: 2.7V to 5.5V

▪ Five switching regulators with adjustable output

RAA271000 contains five high efficiency DC/DC

synchronous buck regulators and two low-dropout

linear regulators (LDO).

▪ V

from 0.3V ~ 3.3V at:

OUT

• 15A (Buck 1)

• 2A (Buck 2-3)

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.

• 4A (Buck 4-5)

▪ Programmable current limits for all bucks

▪ Two linear regulators

• Output 0.6V to 3.6V at 300mA (LDO1-2)

▪ 12-bit analog-to-digital converter for monitoring

▪ Configurable through I C or SPI interface

▪ Programmable power sequence

▪ Supports R-Car SoC sequence of activation

▪ Challenge-response watchdog timer

▪ Dual thermal protection system

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.

▪ 60 ball BGA package, 0.8mm pitch

▪ ASIL-D ISO26262 Development Process

▪ AEC-Q100 qualified (grade 1)

Applications

▪ Automotive vision systems

▪ Automotive LIDAR systems

▪ Ideal power supply for the Renesas V3H SoC
