RST
Active-Low Reset Output. The MAX6730/MAX6732/MAX6734 provide an open-
drain output. The MAX6731/MAX6733/MAX6735 provide a push-pull output.
RST
asserts low when any of the following conditions occur: V
CC
1 or V
CC
2 drops below
its preset threshold, RSTIN drops below its reset threshold, or
MR
is driven low.
Open-drain versions require an external pullup resistor.

WDO
Active-Low Watchdog Output. The MAX6730/MAX6732/MAX6734 provide an open-
drain
WDO
output. The MAX6731/MAX6733/MAX6735 provide a push-pull
WDO
output.
WDO
asserts low when no low-to-high or high-to-low transition occurs on
WDI within the watchdog timeout period (t
WD
) or if an undervoltage lockout
condition exists for V
CC
1, V
CC
2, or RSTIN.
WDO
deasserts without a timeout period
when V
CC
1, V
CC
2, and RSTIN exceed their reset thresholds, or when the manual
reset input is deasserted. Open-drain versions require an external pullup resistor.

MR
Active-Low Manual Reset Input. Drive
MR
low to force a reset.
RST
remains
asserted as long as
MR
is low and for the reset timeout period after
MR
releases
high.
MR
has a 50k
pullup resistor to V
CC
1; leave
MR
open or connect to V
CC
1 if
unused.

WDI
Watchdog Input. If WDI remains high or low for longer than the watchdog timeout
period, the internal watchdog timer expires and the watchdog output asserts low.
The internal watchdog timer clears whenever
RST
asserts or a rising or falling edge
on WDI is detected. The watchdog has an initial watchdog timeout period (35s min)
after each reset event and a short timeout period (1.12s min) after the first valid
WDI transition. Floating WDI does not disable the watchdog timer function.

V
CC
1
Primary Supply Voltage Input. V
CC
1 provides power to the device when it is greater
than V
CC
2. V
CC
1 is the input to the primary reset threshold monitor.

V
CC
2
Secondary Supply Voltage Input. V
CC
2 provides power to the device when it is
greater than V
CC
1. V
CC
2 is the input to the secondary reset threshold monitor.

RSTIN
Undervoltage Reset Comparator Input. RSTIN provides a high-impedance
comparator input for the adjustable reset monitor.
RST
asserts low if the voltage at
RSTIN drops below the 626mV internal reference voltage. Connect a resistive
voltage-divider to RSTIN to monitor voltages higher than 626mV. Connect RSTIN to
V
CC
1 or V
CC
2 if unused.
