The MAX6314 low-power CMOS microprocessor (µP)
s up e rvis ory c irc uit is d e s ig ne d to monitor p owe r
supplies in µP and digital systems. The MAX6314’s
RESET output is bidirectional, allowing it to be directly
connected to µPs with bidirectional reset inputs, such
as the 68HC11. It provides excellent circuit reliability
and low cost by eliminating external components and
adjustments. The MAX6314 also provides a debounced
manual reset input.

two E-clock cycle delay, the processor knows that it
caused the reset itself and can jump to a different vec-
tor and use stored state information to determine what
caused the reset.
The MAX6314 has a reset output consisting of a 4.7kΩ
pull-up resistor in parallel with a P-channel transistor
and an N-channel pull down (Figure 1), allowing this IC
to directly interface with microprocessors (µPs) that
have bidirectional reset pins (see the Reset Output
section).
The problem occurs with faster µPs; two E-clock cycles
is only 500ns at 4MHz. When there are several devices
on the re s e t line , the inp ut c a p a c ita nc e a nd s tra y
capacitance can prevent RESET from reaching the

keeps reset asserted for the reset timeout period (t );
RP
The MAX6314 solves this problem by including a pull-
up transistor in parallel with the recommended 4.7kΩ
resistor (Figure 1). The pull-up resistor holds the output
high until RESET is forced low by the µP reset I/O, or by
the MAX6314 itself. Once RESET goes below 0.5V, a
comparator sets the transition edge flip-flop, indicating
that the next transition for RESET will be low to high. As
soon as RESET is released, the 4.7kΩ resistor pulls
after this interval RESET goes high. If a brownout condi-
tion oc c urs (monitore d volta g e d ip s b e low its p ro-
grammed reset threshold), RESET goes low. Any time
V
CC
dips below the reset threshold, the internal timer
resets to zero and RESET goes low. The internal timer
starts when V returns above the reset threshold, and
CC
RESET remains low for the reset timeout period.
The MAX6314’s RESET output is designed to interface
with µPs that have bidirectional reset pins, such as the
Motorola 68HC11. Like a n op e n-d ra in outp ut, the
MAX6314 allows the µP or other devices to pull RESET
low and assert a reset condition. However, unlike a
standard open-drain output, it includes the commonly
specified 4.7kΩ pull-up resistor with a P-channel active
pull-up in parallel.

4.7kΩ p ull-up a nd the P-c ha nne l tra ns is tor on-
resistance quickly charges stray capacitance on the
reset line, allowing RESET to transition low to high with-
in the required two E-clock period, even with several
devices on the reset line (Figure 2). Once the one-shot
time s out, the P-c ha nne l tra ns is tor turns off. This
process occurs regardless of whether the reset was

RESET. These µPs can often determine if a reset was
asserted by an external device (i.e., the supervisor IC)
or by the µP itself (due to a watchdog fault, clock error,
or other source), and then jump to a vector appropriate
for the source of the reset. However, if the µP does
assert reset, it does not retain the information, but must
determine the cause after the reset has occurred.

being asserted, or the µP or other device asserting
RESET. Because the MAX6314 includes the standard
4.7kΩ pull-up resistor, no external pull-up resistor is
required. To minimize current consumption, the internal
pull-up resistor is disconnected whenever the MAX6314
asserts RESET.
Ma n u a l Re s e t In p u t
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 reset. Reset remains asserted while MR is low,
and for the reset active timeout period after MR returns
high. To minimize current consumption, the internal
4.7kΩ p ull-up re s is tor on RESET is d is c onne c te d
whenever RESET is asserted.
The following procedure describes how this is done
with the Motorola 68HC11. In all cases of reset, the µP
pulls RESET low for about four E-clock cycles. It then
releases RESET, waits for two E-clock cycles, then
checks RESET’s state. If RESET is still low, the µP con-
cludes that the source of the reset was external and,
when RESET eventually reaches the high state, jumps
to the normal reset vector. In this case, stored state

MR has an internal 63kΩ pull-up resistor, so it can be
left open if not used. Connect a normally open momen-
tary switch from MR to GND to create a manual reset
function; external debounce circuitry is not required. If
MR is driven from long cables or if the device is used in
a noisy environment, connecting a 0.1µF capacitor from
MR to ground provides additional noise immunity.

holding RESET low (Figure 3). R1’s value is not critical;
100kΩ is large enough not to load RESET and small
enough to pull RESET to ground.
In addition to issuing a reset to the µP during power-up,
power-down, and brownout conditions, these devices
are relatively immune to short-duration negative-going
transients (glitches). The Typical Operating Character-
