MAX31722MUA+

MAX31722MUA+ is a digital thermometer and thermostat with an SPI/3-wire interface that provides temperature readings that indicate the device's temperature. No additional components are required; the device is truly a temperature-to-digital converter. Temperature readings are communicated from the device over an SPI interface or a 3-wire serial interface. The choice of interface is selectable by the user. For applications that require greater temperature resolution, the user can adjust the readout resolution from 9 to 12 bits. This is particularly useful in applications where thermal runaway conditions must be detected quickly. The thermostat has a dedicated open-drain output (active-low TOUT). Two thermostat operating modes, comparator and interrupt, control thermostat operation based on user-defined non-volatile trip points (THIGH and TLOW). Applications include networking equipment, cellular base stations, industrial equipment, and any thermally sensitive systems.

• Maximize system accuracy in broad range of thermal management applications
