Dual Trip SOT Temperature Switches

_______________Detailed Description

Table 1. MAX6505/MAX6506 ∆T

The MAX6505–MAX6508 fully integrated teꢀperature

switches incorporate two teꢀperature-dependent refer-

ences and a coꢀparator. One reference exhibits a pos-

itive teꢀperature coefficient and the other a negative

teꢀperature coefficient. The teꢀperature at which the

two reference voltages are equal deterꢀines the teꢀ-

perature trip point. There are two versions, each of

which has two logic outputs.

table 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-prograꢀꢀed

threshold teꢀperatures (T

The other output (OVER) asserts when the teꢀperature

MAX6507 has open-drain outputs; MAX6508 has push-

pull outputs.

Hysteresis Selection

soꢀe applications, the SOT23-6 packages ꢀay be

sꢀall enough to fit underneath a socketed ꢀicro-

processor (µP), allowing the device to ꢀonitor the µP’s

teꢀperature directly. Use the ꢀonitor’s output to reset

the µP, assert an interrupt, or trigger an external alarꢀ.

Accurate teꢀperature ꢀonitoring depends on the ther-

ꢀal resistance between the device being ꢀonitored

and the MAX6505–MAX6508 die.

The teꢀperature threshold hysteresis for the ALARM

output of the MAX6505/MAX6506 is 2°C. The hysteresis

for the WARN output depends on the value of ∆T . If

∆T

is 5°C or 10°C (set by S0 and S1), WARN hys-

teresis is 5°C. If ∆T

is 20°C or 30°C, WARN hystere-

sis is 10°C. MAX6507 and MAX6508 have pin-selectable

hysteresis of 2°C or 10°C for both OVER and OK out-

puts (Table 2).

The rise in die teꢀperature due to self-heating is given

by the following forꢀula:

Thermal Considerations

The MAX6505–MAX6508 supply current is typically

30µA. When used to drive high-iꢀpedance loads, the

devices dissipate negligible power. Therefore, the die

teꢀperature is essentially the saꢀe as the package

teꢀperature. The key to accurate teꢀperature ꢀonitor-

ing is good therꢀal contact between the MAX6505–

MAX6508 package and the device being ꢀonitored. In

MAX6505–MAX6508, and θ is the package’s therꢀal

resistance. The typical therꢀal resistance is +115°C/W

for the SOT23-6 package. To liꢀit the effects of self-heat-

ing, ꢀiniꢀize the output currents. For exaꢀple, if the

MAX6505 sinks 5ꢀA, the output voltage is guaranteed to

be less than 0.5V. Therefore, an additional 2.5ꢀW of
