MAXIM MAX6505 User Manual

General Description

The MAX6505–MAX6508 temperature switches have dual
logic outputs that assert when the die temperature cross­es their trip thresholds. Trip thresholds are factory pro­grammed to convenient temperatures in 5°C increments.

The MAX6505/MAX6506 have an ALARM output that
asserts when the temperature is above the factory-pro­grammed thresholds (available from -40°C to +125°C).
They also have a WARN output that asserts when the
temperature is several degrees below the ALARM thresh­old. The difference between the ALARM and WARN
thresholds (ΔT

AW

) is pin selectable to +5°C, +10°C,
+20°C, or +30°C. The MAX6505’s logic outputs are open
drain, while the MAX6506’s logic outputs are push-pull.

The MAX6507 has open-drain outputs (OVER, OK), and
the MAX6508 has push-pull outputs (OVER, OK), each
with two factory-programmed threshold temperatures
(T

OVER

and T

UNDER

) in the wide range of -40°C to
+125°C. The overtemperature output asserts when the
temperature is above T

OVER

. When the temperature is in

the desired window (less than T

OVER

and greater than

T

UNDER

), OK (OK) asserts.

The MAX6505–MAX6508 are accurate to ±0.5°C (typ),
±5.5°C (max). Operating from a +2.5V to +5.5V supply,
these low-cost devices typically consume 30µA supply
current and require no external components for setting
trip points. The MAX6505–MAX6508 are available in a
6-pin SOT23 package.

MAX6505–MAX6508

Dual Trip SOT Temperature Switches

_______________________________________________________________________________________ 5

_______________Detailed Description

The MAX6505–MAX6508 fully integrated temperature
switches incorporate two temperature-dependent refer­ences and a comparator. One reference exhibits a pos­itive temperature coefficient and the other a negative
temperature coefficient. The temperature at which the
two reference voltages are equal determines the tem­perature trip point. There are two versions, each of
which has two logic outputs.

The MAX6505/MAX6506 have a main trip point (T

ALARM

)

and a lower, “warning” trip point (T

WARN

). When the die
temperature rises above these trip points, the ALARM
and WARN outputs are asserted (Figure 1). The differ­ence between the two trip points (ΔT

AW

) is pin selec­table to +5°C, +10°C, +20°C, or +30°C by connecting
the two control pins (S0 and S1) high or low (Table 1).
MAX6505 has open-drain active-low outputs; MAX6506
has push-pull active-high outputs.

The MAX6507/MAX6508 have two factory-programmed
threshold temperatures (T

OVER

and T

UNDER

) and two
outputs (OK and OVER). One output (OK) asserts
when the temperature is between T

OVER

and T

UNDER

.
The other output (OVER) asserts when the temperature
is above T

OVER

. Table 4 shows the hex codes to deter­mine the part numbers associated with specific values
of T

OVER

and T

UNDER

. The first hex code indicates the

lower trip point (T

UNDER

) and the second indicates the

higher trip point (T

OVER

). For example, a part with T

UN-

DER

= -10°C and T

OVER

= +75°C will have the part
number MAX6508UTA04B (Table 4 and Figure 2).
MAX6507 has open-drain outputs; MAX6508 has push­pull outputs.

Hysteresis Selection

The temperature threshold hysteresis for the ALARM
output of the MAX6505/MAX6506 is 2°C. The hysteresis
for the WARN output depends on the value of ΔTAW. If
ΔTAWis 5°C or 10°C (set by S0 and S1), WARN hys-
teresis is 5°C. If ΔTAWis 20°C or 30°C, WARN hystere­sis is 10°C. MAX6507 and MAX6508 have pin-selectable
hysteresis of 2°C or 10°C for both OVER and OK out­puts (Table 2).

Applications Information

Thermal Considerations

The MAX6505–MAX6508 supply current is typically
30µA. When used to drive high-impedance loads, the
devices dissipate negligible power. Therefore, the die
temperature is essentially the same as the package
temperature. The key to accurate temperature monitor­ing is good thermal contact between the MAX6505–
MAX6508 package and the device being monitored. In

some applications, the SOT23 packages may be small
enough to fit underneath a socketed microprocessor
(µP), allowing the device to monitor the µP’s tempera­ture directly. Use the monitor’s output to reset the µP,
assert an interrupt, or trigger an external alarm.
Accurate temperature monitoring depends on the ther­mal resistance between the device being monitored
and the MAX6505–MAX6508 die.

The rise in die temperature due to self-heating is given
by the following formula:

ΔT

J

= P

DISSIPATION

✕

θ

JA

where P

DISSIPATION

is the power dissipated by the
MAX6505–MAX6508, and θJAis the package’s thermal
resistance. The typical thermal resistance is 115°C/W for
the SOT23 package. To limit the effects of self-heating,
minimize the output currents. For example, if the
MAX6505 sinks 5mA, the output voltage is guaranteed to
be less than 0.5V. Therefore, an additional 2.5mW of

power is dissipated within the IC. This corresponds to a
+0.288°C shift in the die temperature in the SOT23.

Power Supply and Bypassing

The MAX6505 and MAX6508 operate from a single­supply voltage in the +2.5V to +5.5V range. Connect a

0.1µF capacitor on the supply voltage line close to the
VCCpin for bypassing.

Low-Cost, Fail-Safe Temperature Monitor

The MAX6505/MAX6506 provide two outputs that can be
used for fail-safe temperature applications (Figure 3). For
example, the first output can activate a fan when the die
temperature exceeds a certain preset temperature. The
second output asserts at a higher temperature that could
be caused by a wide variety of destructive fault condi­tions, including latchup, short circuit, and cooling system
failure. This output can be used to initiate such actions
as shutdown of the entire system (see

Typical Operating

Circuits

)

.

The high-level integration, low cost, and small size of the
MAX6505–MAX6508 facilitate the use of multiple temper­ature monitors to increase system reliability.

Temperature-Window Alarm

The MAX6507 and MAX6508 have an output (OK, OK)
that indicates the die temperature is within the selected
temperature window. This output is asserted when
within the window, and deasserted when outside the
window. Additionally, a second digital output indicates
when the die temperature is above the upper set point.
This is useful in systems where operation is optimized
over a predetermined temperature range. The thermal
overrange signal can be used to assert a thermal shut­down, power-up, recalibration, or other temperature­dependent function (Figure 4 and

Typical Operating

Circuits

).

DESCRIPTION

Changed all leaded parts to lead(Pb)-free parts in the Ordering Information table; in
the Absolute Maximum Ratings section changed the continuous power dissipation
numbers (7.1mW/°C to 8.7mW/°C and 571mW to 696mW) and added the sol dering
temperature; added the Package Information table
