Low-Cost, Microprocessor Supervisory Circuit
Low-Cost, Microprocessor Supervisory Circuit

The SGM706 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 SGM706 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 SGM706 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 SGM706.

The SGM706 is available in a Green SOIC-8 package. The SGM706-S is available in Green SOIC-8 and MSOP-8 packages. They operate over an ambient temperature range of -40 to +85.
