SGM706
Low-Cost, Microprocessor
Supervisory Circuit
GENERAL DESCRIPTION
The SGM706 microprocessor supervisory circuit reduces
the complexity and number of components required to
monitor power-supply and monitor microprocessor
activity. It significantly improves system reliability and
accuracy compared to separate ICs or discrete
components.
The SGM706 provides power-supply monitoring circuitry
that generates a reset output during power-up,
power-down and brownout conditions. The reset output
remains operational with V_CC as low as 1V. Independent
watchdog monitoring circuitry is also provided. This is
activated if the watchdog input has not been toggled
within 1.6 seconds.
In addition, there is a 1.25V threshold detector for
power-fail warning, low-battery detection, or monitoring
an additional power supply. An active-low manual-reset
input (MR) is also included.
The SGM706 is available in Green SOIC-8 package. It
operates over an ambient temperature range of -40℃ to
+85℃.
