RAMSUN recommends sharing a high-precision, low-power, digital temperature sensor that can replace NTC/PTC thermistors, which can be used for temperature measurement in communications, computers, consumer electronics, environmental, industrial, and instrumentation applications. Within the normal operating range of -40°C to +125°C, it can provide a temperature accuracy of ≤±0.5°C and has good temperature linearity.
An extended temperature measurement mode can be provided to extend the temperature measurement range from -55°C to +150°C. The rated operating voltage range is 1.4V~5.5V, and the maximum quiescent current in the entire operating range is 10µA (temperature measurement frequency 4Hz). The 12-bit ADC resolution integrated inside the chip is as low as 0.0625°C. Adopt 1.6mm×1.6mm SOT563/DFNWB package, compatible with SMBus and I2C interface, can mount up to four slaves on one bus, and has SMBus alarm function. Suitable for portable, battery-powered applications; power supply temperature monitoring; thermal protection of computer external equipment; notebook computers; battery management; constant temperature control; temperature of electromechanical equipment;
