What this supervisor does on your board
The voltage threshold is adjustable/selectable via external resistors, giving flexibility across different logic families and supply rails. Operating temperature spans -40°C to 85°C, covering industrial control, outdoor telecom, and factory automation environments. Housed in an 8-pin SOIC package (3.90mm width), it is a surface-mount part that fits standard PCB layouts for supervisor functions. The part is ROHS3 compliant.
Sourcing and lifecycle — active, no LTB risk
The MAX6303ESA+T carries an active lifecycle status from the manufacturer. That means no end-of-life notice is pending, and the part remains available for new designs and production builds. For BOM planning, this removes the obsolescence risk that often forces a last-time-buy scramble on supervisor ICs.
