GENERAL DEscriptION

The SGM708 is an integrated microprocessor supervisory device. Compared with a design using a single IC or discrete components, this integration design has the advantage of improving system stability and accuracy. The SGM708 can be reset under power-up, power-down or even voltage reduction brownout conditions. When VCC is as low as 1V, the reset output can still operate. And it also has a low-level active manual reset (MR) function.

The SGM708 provides a 1.25V threshold detector. When the power supply fails, the battery power is low, or the additional power supply needs to be monitored, this detector can help.

The SGM708 is available in Green SOIC-8 package. It operates over an ambient temperature range of -40℃ to +85℃.
