Detailed Description
Supply Voltages
The MAX6736–MAX6745 μP supervisory circuits main-
tain system integrity by alerting the μP to fault condi-
tions. These devices are optimized for systems that
monitor two or three supply voltages. The reset output
state is guaranteed to remain valid while either V CC 1 or
V CC 2 is above 1.2V.
Threshold Levels
The MAX6736/MAX6737/MAX6740/MAX6741/MAX6743/
MAX6744 input voltage threshold combinations are indi-
cated by a two-letter code in Table 1. The MAX6738/
MAX6739/MAX6742/MAX6745 input voltage thresholds
are indicated by a one-letter code in Table 2. Contact the
factory for the availability of other voltage thresholds.
Reset Output
The MAX6736–MAX6745 provide an active-low reset out-
put ( RESET ). RESET is asserted when the voltage at
either V CC 1 or V CC 2 falls below the voltage threshold
level, RSTIN drops below the threshold, or MR is pulled
low. Once reset is asserted, it stays low for the reset time-
out period. If V CC 1, V CC 2, or RSTIN goes below the reset
threshold before the reset timeout period is completed,
the internal timer restarts. The MAX6736/MAX6738/
MAX6740/MAX6741/MAX6742 have open-drain reset out-
puts, while the MAX6737/MAX6739/MAX6743/MAX6744/
MAX6745 have push-pull reset outputs (Figure 1).
The MAX6740/MAX6741/MAX6742 include a RESET
output with a manual reset detect function. The open-
drain RESET output has an internal 50k ? pullup to
V CC 1. The RESET output is low while the output is
pulled to GND and remains low for at least the manual
reset timeout period after the external GND pulldown is
10
