LM26LV is a low-voltage, high-precision, dual-output, low-power temperature switch, temperature sensor. The temperature trip point (T trip) can be pre-set at the factory for any temperature range from 0°C to 150°C 1℃ Increment. The built-in temperature hysteresis (T HYST) output is stable and maintains at ambient temperature instability.
When the LM26LV temperature switch output asserts in normal operation, the temperature of the mold exceeds the T trip. When the temperature drops below a certain temperature (T Journey - T HYST), the temperature switch output will reset. The OVERTEMP digital output is positively high with the push-pull structure, while the ^OVERTEMP digital output, the low-level effective, open-drain structure.
V Temperature, the analog output, provides an analog output voltage with a negative temperature coefficient - NTC.
The driving trip test input is high: (1) the digital output of the cause in-situ verification assertion, and (2) the threshold voltage V temperature output pin appears, which may be used to verify the temperature trigger point.
The LM26LV's low supply voltage is ideal for system designs with a minimum of 1.8 volts. With its wide operating range, low supply current, and excellent accuracy, it offers temperature switching solutions for a wide range of commercial and industrial applications.
