Looking for Power Supply Supervisor Solution for Agilex-5 SoC (A5EDxxx) with Tight Voltage Tolerance

Hello,

I am working on a design using an Intel Agilex-5 SoC (A5EDxxx) and need to implement supervision of multiple power rails with the following requirements:

• Rails to monitor (with SoC tolerances):
  • 0.8 V ±3%
  • 1 V ±2.5%
  • 1.1 V ±3%
  • 1.2 V ±5%
  • 1.8 V ±2.5%
  • 3.3 V ±3%
• DC/DC or LDO output voltage accuracy: typically ±1%
• Goal: Minimize the number of different supervisor references (prefer adjustable threshold supervisors)
• Constraints: Must account for resistor divider tolerance (for adjustable thresholds) and hysteresis level
• Challenge: I cannot find a reference of supervisor that meets all these constraints, especially for fine tolerances.

What is the recommended supervision architecture for processors (like Agilex-5) with increasingly tight power supply tolerances?

Thank you in advance for your support.

Best regards,
David
