The LM57TPW from Texas Instruments is a versatile temperature switch and analog temperature sensor designed for various applications. This device features a resistor-programmable setpoint, allowing for flexible temperature threshold configuration within a range of -40°C to 150°C. It operates across a wide temperature range of -50°C to 150°C with an accuracy of ±2.3°C for the trip temperature and ±1.3°C for the analog output.
The LM57TPW provides both push-pull and open-drain switch outputs, offering flexibility in system integration. It includes built-in hysteresis and a trip-test pin for in-system testing. The device operates from a supply voltage of 2.4V to 5.5V and consumes a typical supply current of 24µA, minimizing self-heating to under 0.02°C. It is available in an 8-TSSOP package and is designed for surface mount applications.
Key features include short-circuit protection for analog and digital outputs, and a latching function for digital outputs. The low power consumption makes it suitable for battery-powered devices. The analog VTEMP output provides a linear temperature reading, complementing the temperature switch functionality.
