MAX7500MSA+

MAX7500MSA+ is a digital temperature sensor and thermal watchdog with bus lockup protection. This temperature sensor accurately measures temperature and provides an overtemperature alarm/interrupt/shutdown output. This device converts the temperature measurements to digital form using a high-resolution, sigma-delta, analogue-to-digital converter (ADC). The 2-wire serial interface accepts standard write byte, read byte, send byte, and receive byte commands to read the temperature data and configure the behaviour of the open-drain overtemperature shutdown output. Suitable for PCs, servers, office electronics, electronic test equipment and industrial process control applications.
