General Description

The MAX6314 low-power CMOS microprocessor (µP)

supervisory circuit is designed to monitor power 

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.

This device performs a single function: it asserts a reset

signal whenever the V

CC

supply voltage falls below a

preset threshold or whenever manual reset is 

asserted. Reset remains asserted for an internally pro-

grammed interval (reset timeout period) after V

CC

has

risen above the reset threshold or manual reset is

deasserted.

The MAX6314 comes with factory-trimmed reset 

threshold voltages in 100mV increments from 2.5V 

to 5V. Preset timeout periods of 1ms, 20ms, 140ms,

and 1120ms (minimum) are also available. The device

comes in a SOT143 package.

For a µP supervisor with an open-drain reset pin, see

the MAX6315 data sheet.

_______________Detailed Description

The MAX6314 has a reset output consisting of a 4.7k

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).

Reset Output

A µP’s reset input starts the µP in a known state. The

MAX6314 asserts reset to prevent code-execution

errors during power-up, power-down, or brownout 

conditions. RESET is guaranteed to be a logic low for

V

CC

> 1V (see the 

Electrical Characteristics). Once

V

CC

exceeds the reset threshold, the internal timer

keeps reset asserted for the reset timeout period (t

RP

);

after this interval RESET goes high. If a brownout condi-

tion occurs (monitored voltage dips below its pro-

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

CC

returns above the reset threshold, and

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 an open-drain output, 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 4.7k

pull-up resistor with a P-channel active

pull-up in parallel.

This configuration allows the MAX6314 to solve a prob-

lem associated with µPs that have bidirectional reset

pins in systems where several devices connect to

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. 

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

information is erased and processing begins from

scratch. If, on the other hand, RESET is high after the

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 problem occurs with faster µPs; two E-clock cycles

is only 500ns at 4MHz. When there are several devices

on the reset line, the input capacitance and stray

capacitance can prevent RESET from reaching the

logic-high state (0.8 x V

CC

) in the allowed time if only a

passive pull-up resistor is used. In this case, all resets

will be interpreted as external. The µP is guaranteed to

sink only 1.6mA, so the rise time cannot be much

reduced by decreasing the recommended 4.7k

pull-up resistance. 

The MAX6314 solves this problem by including a pull-

up transistor in parallel with the recommended 4.7k

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 4.7k

resistor pulls

RESET up toward V

CC

. When RESET rises above 0.5V,

the active P-channel pull-up turns on for the 2µs 

duration of the one-shot. The parallel combination of the

4.7k

pull-up and the P-channel transistor 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

times out, the P-channel transistor turns off. This

process occurs regardless of whether the reset was

caused by V

CC

dipping below the reset threshold, MR

being asserted, or the µP or other device asserting

RESET. Because the MAX6314 includes the standard

4.7k

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.

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 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

4.7k

pull-up resistor on RESET is disconnected 

whenever RESET is asserted.

_______________________________________________________________________________________

MR has an internal 63k

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.

__________Applications Information

Negative-Going V

CC

Transients

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-

istics show the Maximum Transient Duration vs. Reset

Threshold Overdrive, for which reset pulses are not

generated. The graph was produced using negative-

going pulses, starting at V

RST

max and ending below

the programmed reset threshold by the magnitude 

indicated (reset threshold overdrive). The graph shows

the maximum pulse width that a negative-going V

CC

transient may typically have without causing a reset

pulse to be issued. As the amplitude of the transient

increases (i.e., goes farther below the reset threshold),

the maximum allowable pulse width decreases. A 0.1µF

bypass capacitor mounted close to V

CC

provides addi-

tional transient immunity.

Ensuring a Valid 

RESET Output

Down to V

CC

= 0V

When V

CC

falls below 1V, RESET no longer sinks 

current—it becomes an open circuit. Therefore, high-

impedance CMOS-logic inputs connected to RESET

can drift to undetermined voltages. This presents no

problem in most applications, since most µP and other

circuitry is inoperative with V

CC

below 1V. However, in

applications where RESET must be valid down to 

V

CC 

= 0V, adding a pull-down resistor to RESET will

cause any stray leakage currents to flow to ground,

holding RESET low (Figure 3). R1’s value is not critical;

100k

is large enough not to load RESET and small

enough to pull RESET to ground.
