The LM57FPWR from Texas Instruments is a precision, dual-output temperature switch with an integrated analog temperature sensor. This device is designed for applications requiring a programmable trip temperature, adjustable via external resistors, with a setpoint range from -40°C to 150°C. The operating temperature range for the device itself is -50°C to 150°C.
Key electrical features include a supply voltage range of 2.4V to 5.5V and a typical supply current of 24µA. The output stage provides both open-drain and push-pull options, with an active high/low output function. Accuracy for the analog temperature sensor output is ±1.3°C within the -40°C to +150°C range, while the trip temperature accuracy is ±2.3°C over the same range. The device also includes features like built-in hysteresis and a trip-test pin for in-system testing.
Packaged in an 8-TSSOP, the LM57FPWR is designed for surface mount applications. Its low power consumption minimizes self-heating, ensuring accurate temperature readings. The combination of a temperature switch and an analog sensor in a single package makes it suitable for various thermal monitoring and control tasks.
