Supervisor IC for single-rail monitoring
The MAX6457UKD0C+T: The voltage threshold is adjustable or selectable, giving the board designer flexibility to set the trip point for the specific rail being monitored.
50 µs reset timeout and wide temperature range
The reset timeout is 50 µs typical, which means the output holds the reset state for that duration after the monitored voltage returns above the threshold — long enough for most power supplies to stabilize before the processor starts executing code. Operating temperature spans -40°C to +125°C (TA), covering industrial and automotive ambient conditions where the supervisor must remain reliable under thermal cycling.
It is ROHS3 compliant, which simplifies BOM compliance for markets requiring restriction of hazardous substances.
