The MAX6715–MAX6729 microprocessor (µP) supervi-
sory circuits maintain system integrity by alerting the µP
to fault conditions. These ICs are optimized for systems
that monitor two or three supply voltages. The output-
reset state is guaranteed to remain valid while either
V
Input voltage threshold level combinations are indicat-
ed by a two-letter code in the Reset Voltage Threshold

Suffix Guide (Table 1). Contact factory for availability of
other voltage threshold combinations.
The MAX6715–MAX6729 provides an active-low reset
output (RST) and the MAX6725/MAX6726 provides
both an active-high (RST) and an active-low reset out-
put (RST). RST, RST, RST1, and RST2 are asserted
when the voltage at either V
voltage threshold level, RSTIN drops below threshold,
or MR is pulled low. Once reset is asserted it stays low
for the reset timeout period (see Table 2). If V

the reset timeout period is completed, the internal timer
