LM26NV  
SOT-23, ±3°C Accurate, Factory Preset Thermostat  
(LM26 without VTEMP output)  
General Description  
The LM26NV is a precision, single digital-output, low-power

thermostat comprised of an internal reference, DAC, temper-  
ature sensor and comparator. Utilizing factory programming,  
it can be manufactured with different trip points as well as  
different digital output functionality. The trip point (TOS) can  
be preset at the factory to any temperature in the range of  
−55°C to +110°C in 1°C increments. The LM26NV has one  
digital output (OS/OS/US/US) and one digital input (HYST).  
The digital output stage can be preset as either open-drain or  
push-pull. In addition, it can be factory programmed to be ac-  
tive HIGH or LOW. The digital output can be factory pro-  
grammed to indicate an over temperature shutdown event  
(OS or OS) or an under temperature shutdown event (US or  
US). When preset as an overtemperature shutdown (OS), it  
will go LOW to indicate that the die temperature is over the  
internally preset TOS and go HIGH when the temperature  
goes below (TOS–THYST). Similarly, when preprogrammed as  
an undertemperature shutdown (US) it will go HIGH to indi-  
cate that the temperature is below TUS and go LOW when the  
temperature is above (TUS+THYST). The typical hysteresis,  
THYST, can be set to 2°C or 10°C and is controlled by the state  
of the HYST pin.
