The MAX6759UTLD0+T from Maxim Integrated is a voltage window detector — a precision monitor that asserts an output when the supply voltage strays outside a fixed upper and lower threshold. Packaged in a SOT23-6, it is sized for compact board layouts where a single supervisor IC replaces a comparator pair and reference. The window-detection architecture suits power-rail monitoring in portable instrumentation, industrial sensors, and battery-powered gear where undervoltage and overvoltage both need a hard fault flag.
Lifecycle status is Active per Maxim's product record. No last-time-buy or end-of-life notice is in force.
Sourcing and procurement
This is an active part with no known supply constraints; the strip shipping format is typical for small-to-medium volume assembly runs.
