RAA271005 General Purpose IC for Power Management Automotive Applications Short-Form Datasheet
series.
■The RAA271005 contains five DC/DC switching regulators and 6 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 AEC-Q100 Grade 1 operation supporting an ambient temperature range of -40°C to 125°C.
