MAX6310 feature an active-low, complementary output
structure that both sinks and sources current, and the
MAX6311/MAX6312/MAX6313 have an active-high com-
plementary reset output.
The MAX6305/MAX6308/MAX6311 switch from under-
voltage lockout operation to normal operation between
1.5V < V CC < 2.5V. Below 1.5V, V CC undervoltage-
lockout mode asserts RESET . Above 2.5V, V CC normal-
operation mode asserts reset if RST IN_ falls below the
RST IN_ threshold.

Manual-Reset Input
(MAX6306/MAX6309/MAX6312)
Many μP-based products require manual-reset capability,
allowing an operator or external logic circuitry to initiate a
reset. A logic low on MR asserts reset. Reset remains
asserted while MR is low, and for a reset active timeout
period (t RP ) after MR returns high. This input has an inter-
nal 63.5k ? pull-up resistor, so it can be left open if it is not
used. MR can be driven with TTL-logic levels in 5V sys-
tems, with CMOS-logic levels in 3V systems, or with open-
drain/collector output devices. Connect a normally open

momentary switch from MR to GND to create a manual-

Figure 1. Functional Diagram
a noisy environment, connecting a 0.1μF capacitor from
MR to ground provides additional noise immunity.
The MR pin has internal ESD-protection circuitry that may
be forward biased under certain conditions, drawing
excessive current. For example, assume the circuitry driv-
ing MR uses a +5V supply other than V CC . If V CC drops or
browns out lower than +4.7V, MR ’s absolute maximum rat-
ing is violated (-0.3V to (V CC + 0.3V)), and undesirable
current flows through the ESD structure from MR to V CC .
To avoid this, it is recommended that the supply for the MR
pin be the same as the supply monitored by V CC . In this
way, the voltage at MR will not exceed V CC .
Adjustable Reset Inputs
The MAX6305–MAX6313 each have one or more reset
inputs (RST IN_ /OVRST IN). These inputs are com-
pared to the internal reference voltage (Figure 1).
V TH = ________ x V RSTH
Connect a resistor voltage divider to RST IN_ such that
V RST IN_ falls below V RSTH (1.23V) when the monitored
voltage (V IN ) falls below the desired reset threshold
(V TH ) (Figure 2). Calculate the desired reset voltage
with the following formula:
