.The LM339LVPWR is a low-voltage, 14-pin thin shrink small outline package (TSSOP) comparator manufactured by Texas Instruments. This comparator is designed for economical, general-purpose use in a variety of applications. It features fast response time, low-power consumption, and high-level output current drive capability. It operates over the temperature range of -40°C to +125°C and accepts single or dual inputs. Its design allows the comparator to signal when a user-defined voltage limit is exceeded, making it ideal for level detection, voltage monitoring, and over-temperature protection in applications such as automotive, fax machines, and temperature sensing. The LM339LVPWR also provides protection against damage due to surge currents, shorts, and over-temperature conditions. The comparator is also designed for low-voltage operation, allowing it to be used in a variety of power supply systems.
