The temperature trip point • Latching Function: Device Can Latch the Over (TTRIP) can be preset at the factory to any Temperature Condition temperature in the range of 0°C to 150°C in 1°C increments. Built-in temperature hysteresis (THYST) • Push-Pull and Open-Drain Temperature Switch keeps the output stable in an environment of Outputs temperature instability. • Wide Trip Point Range of 0°C to 150°C In normal operation the LM26LV/LM26LV-Q1 • Very Linear Analog VTEMP Temperature Sensor temperature switch outputs assert when the die Output temperature exceeds TTRIP. The temperature switch • VTEMP Output Short-Circuit Protected outputs will reset when the temperature falls below a temperature equal to (TTRIP − THYST). The • Accurate Over −50°C to 150°C Temperature OVERTEMP digital output, is active-high with a push- Range pull structure, while the OVERTEMP digital output, is • 2.2 mm by 2.5 mm (typ) WSON-6 Package active-low with an open-drain structure. • Excellent Power Supply Noise Rejection The analog output, VTEMP, delivers an analog output • LM26LVQISD–130 and LM26LVQISD-135 are voltage with Negative Temperature Coefficient (NTC). AEC-Q100 Grade 0 Qualified and are Driving the TRIP TEST input high: (1) causes the Manufactured on an Automotive Grade Flow. digital outputs to be asserted for in-situ verification For Other Trip Points, Contact Your Sales and, (2) causes the threshold voltage to appear at the Office. VTEMP output pin, which could be used to verify the temperature trip point. APPLICATIONS The LM26LV/LM26LV-Q1's low minimum supply • Cell Phones and Wireless Transceivers voltage makes it ideal for 1.8 Volt system designs. Its • Digital Cameras wide operating range, low supply current, and excellent accuracy provide a temperature switch • Battery Management solution for a wide range of commercial and industrial • Automotive applications. • Disk Drives • Games and Appliances Key Specifications Supply Voltage 1.6V to 5.5V Supply Current 8 μA (typ) Accuracy, Trip Point Temperature 0°C to 150°C ±2.2°C 0°C to 150°C ±2.3°C Accuracy, VTEMP 0°C to 120°C ±2.2°C −50°C to 0°C ±1.7°C VTEMP Output Drive ±100 μA Operating Temperature −50°C to 150°C Hysteresis Temperature 4.5°C to 5.5°C 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
