The MAX705-MAX708/MAX813L are low-cost µP supervisory circuits that monitor power-supply and battery functions, improving system reliability and accuracy.
The MAX705‑MAX708/MAX813L family provides low‑cost µP supervisory circuits that monitor power‑supply and battery functions, offering reset output, watchdog timer, voltage threshold detection and manual‑reset input. The devices improve system reliability and reduce component count in microprocessor‑based designs.
The document includes a general description, functional features, pin‑out diagrams, electrical characteristics, typical operating circuits, detailed reset and watchdog operation, power‑fail comparator usage, packaging information and ordering details for the eight‑pin DIP, SO and µMAX packages.
