The MAX7500 temperature sensor accurately measure temperature and provide an overtemperature alarm/interrupt/shutdown output. This device converts the temperature measurements to digital form using a high-resolution, sigma-delta, analog-to-digital converter (ADC). Communication is through an I²C-compatible 2-wire serial interface. The MAX7500 integrates a timeout feature that offers protection against I²C bus lockups. The MAX7503/MAX7504 do not include the timeout feature. 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 behavior of the open-drain overtemperature shutdown output. The MAX7500 features three address select lines. The MAX7500 3.0V to 5.5V supply voltage range, low 250µA supply current, and a lockup-protected I²C-compatible interface make it ideal for a wide range of applications, including personal computers (PCs), electronic test equipment, and office electronics. The MAX7500 is available in 8-pin µMAX® package and operate over the -40°C to +125°C temperature range.
