SGM800

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

threshold. The reset output remains asserted for the

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 is

specified over an ambient temperature range of -40

℃ to

+85

℃.
