DESCRIPTION
The LM26LV/LM26LV-Q1 is a low-voltage, precision,
dual-output, low-power temperature switch and
temperature sensor. The temperature trip point
(T_TRIP) 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 (T_HYST)
keeps the output stable in an environment of
temperature instability.
In normal operation the LM26LV/LM26LV-Q1
temperature switch outputs assert when the die
temperature exceeds T_TRIP. The temperature switch
outputs will reset when the temperature falls below a
temperature equal to (T_TRIP − T_HYST). 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, V_TEMP, delivers an analog output
voltage with Negative Temperature Coefficient (NTC).
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
V_TEMP output pin, which could be used to verify the
temperature trip point.
The LM26LV/LM26LV-Q1'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.
