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