GENERAL DEscriptION

The SGM706B is an integrated microprocessor supervisory device. Compared with the design using a single IC or discrete components, this integration design has the advantage of improving system stability and accuracy. The SGM706B 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 nMR function.

The SGM706B provides an independent watchdog monitoring circuit, which can activate this function when its power input has not toggled for more than 1.6s.

When the power supply fails, the battery power is low, or the additional power supply needs to be monitored, it can be realized by the 1.25V threshold detector of the SGM706B.

The SGM706B is available in Green UTDFN-1.5×1.5-8L, SOIC-8 and MSOP-8 packages. It operates over an ambient temperature range of -40℃ to +125℃.
