    SGM800

    Low-Power, SOT μP Reset Circuit with Capacitor-Adjustable Reset Timeout Delay
     
    Low-Power, SOT μP Reset Circuit with Capacitor-Adjustable Reset Timeout Delay
    GENERAL DESCRIPTION

    The SGM800 low-power micro-processor supervisor circuit monitors system voltages from 1.6V to 5V. This device performs a single function: it asserts a reset signal whenever the VCC supply voltage falls below its reset threshold. The reset output remains asserted for the reset timeout period after VCC rises above the reset threshold. The reset timeout is externally set by a capacitor to provide more flexibility.

    The SGM800 has an active-low, open-drain reset output. It is available in Green SOT-23-5 package and operates over a temperature range of -40 to +85.
