What the MAX6708YKA does on your board
The MAX6708YKA monitors two supply rails — one at a fixed 2.19V threshold and a second adjustable via external resistors — and asserts both active-high and active-low reset outputs when either rail drops below its threshold. The 140ms minimum reset timeout holds the system in reset long enough for all rails to stabilise after power-up.
Temperature grade and where it fits
Rated for -40°C to 125°C ambient, the MAX6708YKA covers the full industrial temperature span and reaches into automotive under-hood environments. That makes it a candidate for engine-control modules, transmission controllers, and any outdoor telecom or factory-floor equipment where the board sees both cold starts and under-hood heat soak. The SOT-23-8 footprint keeps the layout compact — no extra board area for a supervisor that has to live near the processor.
Reset outputs — active high and active low on the same chip
Both an active-high and an active-low reset output are available from the same device, each driven by a push-pull stage. That saves an external inverter when the processor expects a high-true reset and a peripheral expects a low-true reset, or when you need to drive two different reset domains from one supervisor. No open-drain pull-up resistors needed — the push-pull outputs drive rail-to-rail.
Lifecycle and sourcing reality
The one catch is the RoHS non-compliant marking — if your BOM requires full RoHS exemption documentation or a lead-free assembly profile, verify that the non-compliant status is acceptable for your market and your customer's requirements. For most industrial and automotive builds where leaded solder is still permitted, this is not a blocker.
