NAME
MR
FUNCTION
Manual Reset Input. Pull MR low to manually reset the device. Reset
remains asserted for the reset timeout period after MR is released.
Reset Input. High-impedance input to the adjustable reset comparator.
1
RESET IN
Connect RESET IN to the center point of an external resistor-divider to
set the threshold of the externally monitored voltage.
1
SET0
Logic Input. SET0 selects watchdog window ratio or disables the
watchdog timer. See Table 1.
Watchdog Timeout Input.
MAX6746–MAX6751: Connect a capacitor between SWT and ground to
set the basic watchdog timeout period (t WD ). Determine the period by
the formula t WD = 5.06 x 10 6 x C SWT with t WD in seconds and C SWT in
Farads. Extend the basic watchdog timeout period by using the WDS
input. Connect SWT to ground to disable the watchdog timer function.

SWT
MAX6752/MAX6753: Connect a capacitor between SWT and ground to
set the slow watchdog timeout period (t WD2 ). Determine the slow
watchdog period by the formula: t WD2 = 0.65 x 10 9 x C SWT with t WD2 in
seconds and C SWT in Farads. The fast watchdog timeout period is set
by pinstrapping SET0 and SET1 (Connect SET0 high and SET1 low to
disable the watchdog timer function.) See Table 1.
Reset Timeout Input. Connect a capacitor from SRT to GND to select

the reset timeout period. Determine the period as follows: t RP = 5.06 x
