Dual Trip SOT Temperature Switches  
General Description  
Features  
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

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.  
*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 SOT23-6 package with a +55°C threshold (Table 3). Contact  
the factory for pricing and availability of temperature versions  
(minimum order 10,000 pieces).
