概述 |
the max823/max824/max825* microprocessor (µp) supervisory circuits combine reset output, watchdog, and manual reset input functions in 5-pin sot23 and sc70 packages. they significantly improve system reliability and accuracy compared to separate ics or discrete components. the max823/max824/max825 are specifically designed to ignore fast transients on vcc.
seven preprogrammed reset threshold voltages are available (seereset threshold table). all three devices have an active-low reset output, which is guaranteed to be in the correct state for vccdown to 1v. the max823 also offers a watchdog input and manual reset input. the max824 offers a watchdog input and a complementary active-high reset. the max825 offers a manual reset input and a complementary active-high reset. the selector guide explains the functions offered in this series of parts. |
