SGM804

Low-Power, SOT µP Reset Circuit with

Capacitor-Adjustable Reset Timeout Delay

GENERAL DESCRIPTION

FEATURES

The SGM804 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 V_CCsupply voltage falls below its reset

threshold. The reset output remains asserted for the

reset timeout period after V_CCrises above the reset

threshold. The reset timeout is externally set by a

capacitor to provide more flexibility.
