Overview

The Flexible 6-Channel Power Sequencer is based on Renesas' general-purpose RL78/G12 microcontroller and six discrete DC/DC regulators with integrated power MOSFETs. For ease of use, a low-IQ low-dropout regulator (LDO) with fixed output voltage for microcontroller supply is utilized. The development kit allows users to perform two functions, a power-up sequence and a power-down sequence, using the graphical user interface (GUI) targeted for their specific application. This proprietary power sequencing solution offers great flexibility and is scalable to a very broad range of FPGA and system-on-chip (SoC) applications.

Features

  • Power On/Off sequence with loads
  • Configurable delays (On/Off transition times)
  • Power good signals for each regulator
  • Voltage levels of all 6 channels against loads
