The RAA270000KFT is a Power Management IC (PMIC) for the automotive RH850 microcontroller series. The RAA270000KFT contains two integrated current mode DC-DC converters, four low dropout linear regulators (LDOs), and two linear trackers. The switching frequency of the DC-DC converters is typically 2.1MHz. Also, several monitor functions and diagnostic functions such as over-voltage and under-voltage detection of the regulators and watchdog for monitoring external microcontrollers are implemented. The input voltage of the RAA270000KFT, the output of all regulators, and the internal analog voltage corresponding to temperature can be monitored through ADCs in an external microcontroller. Since the RAA270000KFT includes a power-up/down sequence controller, users can reduce external components for controlling the target microcontroller power-up/down sequence.
