MAX818M Datasheet (Maxim) - +5V Microprocessor Supervisory Circuits

MAX818M, +5V Microprocessor Supervisory Circuits

The MAX817/MAX818/MAX819 microprocessor (µP) supervisory circuits simplify power-supply monitoring, battery control, and chip-enable gating in µP systems by reducing the number of components required.

These devices are designed for use in +5V-powered systems.

Low supply current (11µA typical) and sm
