SGM706

Low-Cost, Microprocessor

Supervisory Circuit

GENERAL DESCRIPTION

FEATURES

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.

● Precision Supply-Voltage Monitor

4.65V for SGM706-L

4.40V for SGM706-M

4.0V for SGM706-J

3.08V for SGM706-T

2.93V for SGM706-S

2.63V for SGM706-R

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_CCas 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.

● Guaranteed

Valid at V_CC= 1V

RESET

● 200ms Reset Pulse Width

● Debounced TTL/CMOS-Compatible

Manual-Reset Input

● Independent Watchdog Timer (1.6sec) Timeout

● Voltage Monitor for Power-Fail or Low-Battery

Warning

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

● -40℃ to +85℃ Operating Temperature Range

● SGM706 is Available in Green SOIC-8 Package

● SGM706-S is Available in both Green SOIC-8 and

MSOP-8 Packages

input ( ) is also included.

The SGM706 is available in Green SOIC-8 package.

The SGM706-S is available in both Green SOIC-8 and

MSOP-8 packages. They operate over an ambient

temperature range of -40℃ to +85℃.
