2.93V threshold, two monitored channels
The MAX6306UK29D3+T is a multi-voltage supervisor from Analog Devices that monitors two supply voltages — one fixed at 2.93V and a second adjustable via an external resistor divider. This makes it a fit for dual-rail systems where the core and I/O voltages need independent supervision with a single IC. That 140ms timeout ensures the downstream processor sees a clean, glitch-free power-good signal before the reset de-asserts.
The commercial temperature grade (0°C to 70°C) limits it to indoor, controlled-environment equipment — not for extended industrial or automotive ambient ranges.
