Overview
Description
Today's mid- to high-end programmable logic controller (PLC) solutions implement powerful FPGAs or SoCs to enable state-of-the-art industrial automation equipment. Therefore, to fulfill the required power sequencing of such demanding components, a flexible setup based on a general-purpose microcontroller and discrete DC/DC regulators (with integrated power MOSFETs) enable an ultimate scalable power sequencing solution for a broad range of FPGA and SoC applications, while maintaining ease of use and low risk of failures during implementation.
System Benefits:
- Universal power supply with a wide input voltage range from 4.5VDC to 24VDC.
- Discrete DC/DC regulators for easy implementation.
- Low-Iq LDO with fixed output voltage for microcontroller supply.
- General-purpose RL78/G12 microcontroller in a 32-pin package.
- DataFlash enables non-volatile data storage of parameters.
- Flexible, programmable delays for Power-ON and Power-OFF events.
- Monitoring of main input voltage via ADC of the microcontroller.
- Reading the Power Good signals of each DC/DC converter.
- Redundant monitoring of power rails with NCU-integrated 10-bit ADC to detect supply rail variations.
Applications
Applications
- All mid- and high-end applications leveraging FPGAs, SoCs, ASICs, MPUs, or communication DSPs which require dedicated power sequencing of their multiple power supply rails.
