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 (∆T

+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

(TOVER and TUNDER) in the wide range of -40°C to

+125°C. The overtemperature output asserts when the

temperature is above TOVER. When the temperature is in

the desired window (less than TOVER and greater than

TUNDER), 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.
