The LM26LV is a low-voltage, precision, dual-output, low-power temperature switch and temperature sensor. The temperature trip point (TTRIP) can be preset at the factory to any temperature in the range of 0°C to 150°C in 1°C increments. Built-in temperature hysteresis (THYST) keeps the output stable in an environment of temperature instability. In normal operation the LM26LV temperature switch outputs assert when the die temperature exceeds TTRIP. The temperature switch outputs will reset when the temperature falls below a temperature equal to (TTRIP − THYST). The OVERTEMP digital output, is active-high with a push-pull structure, while the ^OVERTEMP digital output, is active-low with an open-drain structure. An analog output, VTEMP, delivers an analog output voltage which is inversely proportional to the measured temperature. Driving the TRIP TEST input high: (1) causes the digital outputs to be asserted for in-situ verification and, (2) causes the threshold voltage to appear at the VTEMP output pin, which could be used to verify the temperature trip point. The LM26LV's low minimum supply voltage makes it ideal for 1.8 Volt system designs. Its wide operating range, low supply current , and excellent accuracy provide a temperature switch solution for a wide range of commercial and industrial applications.
