FEATURES
DESCRIPTION
The LM26LV/LM26LV-Q1 is a low-voltage, precision,
dual-output, low-power temperature switch and
temperature sensor. The temperature trip point

•
Wide Trip Point Range of 0°C to 150°C
In normal operation the LM26LV/LM26LV-Q1
temperature switch outputs assert when the die
temperature exceeds TTRIP. The temperature switch
outputs will reset when the temperature falls below a

Excellent Power Supply Noise Rejection
The analog output, VTEMP, delivers an analog output
voltage with Negative Temperature Coefficient (NTC).
LM26LVQISD–130 and LM26LVQISD-135 are
AEC-Q100 Grade 0 Qualified and are
Manufactured on an Automotive Grade Flow.
For Other Trip Points, Contact Your Sales
Office.
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.
APPLICATIONS
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.
