Three-rail supervisor in a six-pin SOT
The MAX6719UTSHD3-T from Maxim Integrated is a multi-voltage supervisor that keeps an eye on three supply rails simultaneously. It asserts a reset signal—active-low, open-drain—when any monitored voltage drops below its threshold, and holds reset for a minimum of 140ms after all rails recover. This part is built for systems that need reliable power-up sequencing and brown-out protection across multiple voltage domains.
Package and footprint
Housed in a SOT-23-6 package (supplier device package same), this supervisor takes up minimal board space—roughly 3×3 mm. The six-pin layout includes the three voltage inputs, reset output, ground, and supply. Surface-mount assembly is standard; no special reflow profile needed beyond typical lead-free or tin-lead solder processes.
Temperature range and environment
Rated for -40°C to 85°C ambient, the MAX6719UTSHD3-T fits industrial and commercial environments—motor drives, base stations, industrial controllers, and networking gear. The extended temperature span covers most factory-floor and outdoor telecom enclosures without needing a mil-spec part.
RoHS status—plan ahead
This part is marked RoHS non-compliant. If your assembly line or customer requires lead-free, RoHS-compliant components, this supervisor will not pass incoming inspection. Factor that into your BOM review early—retrofitting a substitute after layout can be costly.
Sourcing and lifecycle
For new designs or production replenishment, this part is available to source through independent distribution—we quote to order against an RFQ, confirming availability and current pricing at quote time.
