Low-Cost, +2.7V to +5.5V, Micropower  
Temperature Switches in SOT23 and TO-220  
________________General Description  
____________________________Features  
The MAX6501–MAX6504 low-cost, fully integrated tem-  
perature switches assert a logic signal when their die  
temperature crosses a factory-programmed threshold.  
Operating from a +2.7V to +5.5V supply, these devices  
feature two on-chip, temperature-dependent voltage  
references and a comparator. They are available with  
factory-trimmed temperature trip thresholds from -45°C  
to +115°C in 10°C increments, and are accurate to  
0.5°C ꢀtypꢁ or 6°C ꢀmaꢂꢁ. These devices reꢃuire no  
eꢂternal components and typically consume 30µA sup-  
ply current. Hysteresis is pin-selectable at +2°C or  
+10°C.

SOT23-5 and TO220-7 Packages  
The MAX6501/MAX6503 have an active-low, open-drain  
output intended to interface with a microprocessor ꢀµPꢁ  
reset input. The MAX6502/MAX6504 have an active-  
high, push-pull output intended to directly drive fan-  
control logic. The MAX6501/MAX6502 are offered with  
hot-temperature thresholds ꢀ+35°C to +115°Cꢁ, assert-  
ing when the temperature is above the threshold. The  
MAX6503/MAX6504 are offered with cold-temperature  
thresholds ꢀ-45°C to +15°Cꢁ, asserting when the tem-  
perature is below the threshold.

The MAX6501–MAX6504 are offered in eight standard  
temperature versions; contact the factory for pricing  
and availability of nonstandard temperature versions.  
They are available in 5-pin SOT23 and 7-pin TO-220  
packages.  
Typical Operating Circuit  
*These parts are offered in eight standard temperature versions  
with a minimum order of 2,500 pieces. To complete the suffix  
information, add P or N for positive or negative trip temperature,  
and select an available trip point in degrees centigrade. For  
example, the MAX6501UKP065-T describes a MAX6501 in a  
SOT23-5 package with a +65°C threshold. Contact the factory for  
pricing and availability of nonstandard temperature versions (mini-  
mum order 10,000 pieces).
