The LM26LV and LM26LV-Q1 are low-voltage, precision, dual-output, low-power temperature switches and temperature sensors. 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 or LM26LV-Q1 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.

The analog output, VTEMP, delivers an analog output voltage with Negative Temperature Coefficient (NTC).

Driving the TRIP_TEST input high causes the digital outputs to be asserted for in-situ verification and causes the threshold voltage to appear at the VTEMP output pin, which could be used to verify the temperature trip point.

The LM26LV’s and LM26LV-Q1’s low minimum supply voltage makes them ideal for 1.8-V system designs. The wide operating range, low supply current, and excellent accuracy provide a temperature switch solution for a wide range of commercial and industrial applications.
