MAXIM INTEGRATED 电源监控芯片 MAX818LCSA

MAX818LCSA概述

    Product Overview
    The MAX817, MAX818, and MAX819 microprocessor (µP) supervisory circuits represent a series of integrated chips specifically designed to monitor and manage the performance of microprocessors in +5V-powered systems. These devices consolidate multiple critical supervisory functions such as reset management, watchdog functionality, and battery switching, significantly simplifying system design. The low quiescent supply current of 11µA makes them ideal for battery-operated applications. Additionally, they come equipped with a unique backup-battery switchover mechanism that allows the battery voltage to exceed VCC.
    Product Types and Applications:
    - Product Types: MAX817, MAX818, MAX819.
    - Primary Functions: Power-supply monitoring, battery control, and chip-enable gating.
    - Applications: Embedded controllers, intelligent instruments, critical microprocessor monitoring, portable equipment, and battery-powered computers.
