Dual Trip SOT Temperature Switches

General Description

The MAX6505–MAX6508 temperature switches have dual

logic outputs that assert when the die temperature cross-

es their trip thresholds. Trip thresholds are factory pro-

grammed to convenient temperatures in 5°C increments.

The MAX6505/MAX6506 have an ALARM output that

asserts when the temperature is above the factory-pro-

grammed 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 thresh-

old. The difference between the ALARM and WARN

thresholds (ΔT

) 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

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

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.

Note:

To complete the suffix information for the MAX6505/

MAX6506, add P or N for positive or negative trip tempera-

ture, and select an available trip point in degrees centigrade.

For example, the MAX6505UTP055+T describes a MAX6505 in

a SOT23 package with a +55°C threshold (Table 3). Contact

the factory for pricing and availability of temperature versions

(minimum order 10,000 pieces).
