Manual Reset Input
Many μP-based products require manual reset capabil-
ity, allowing the operator, a test technician, or external
logic circuitry to initiate a reset. A logic-low on MR
asserts the reset output, clears the watchdog timer,
and deasserts the watchdog output. Reset remains
V EXT_TH
asserted while MR is low and for the reset timeout peri-
od (t RP ) after MR returns high. An internal 50k ? pullup
resistor allows MR to be left open if unused. Drive MR
with CMOS-logic levels or with open-drain/collector out-

puts. Connect a normally open momentary switch from
MR to GND to create a manual reset function; external
debounce circuitry is not required. Connect a 0.1μF
capacitor from MR to GND to provide additional noise
immunity when driving MR over long cables or if the
device is used in a noisy environment.
Adjustable Input Voltage (RSTIN)
The MAX6734A/MAX6735A provide an additional high-
impedance comparator input with a 626mV threshold to
monitor a third supply voltage. To monitor a voltage
higher than 626mV, connect a resistive divider to the
circuit as shown in Figure 2 to establish an externally
controlled threshold voltage, V EXT_TH .
