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
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 TTL or CMOS-logic levels or with open-drain/col-
lector outputs. Connect a normally open momentary
switch from
MR
to GND to create a manual reset func-
tion; 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 MAX6734/MAX6735 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
.
