Overview
Description
The RAA270005KFP is a Power Management IC (PMIC) for automotive RH850 microcontroller series. The RAA270005KFP contains one boost DC-DC converter with an external MOSFET, one buck DC-DC converter as a pre-regulator , two low dropout linear regulators (LDOs) and two linear trackers. The switching frequency of the boost DC-DC converter and buck DC-DC converter is typical 420kHz and 2.1MHz respectively. 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 RAA270005KFP, the output of all regulators, and internal analog voltage corresponding to temperature can be monitored through ADCs in external microcontroller. Since the RAA270005KFP includes a power-up/down sequence controller, users can reduce external components for controlling the target microcontroller power-up/down sequence. And the RAA270005KFP can control an external backup-power for microcontroller.
