RAA270000KFT

Product Status: Mass Production

OVERVIEW

The RAA270000KFT is a Power Management IC (PMIC) for 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 typical 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 microcontroller are implemented. The input voltage of the RAA270000KFT, the output of all regulators, and internal analog voltage corresponding to temperature can be monitored through ADCs in 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.
