MAX31723PMB1#

MAX31723PMB1# is a peripheral module that provides the necessary hardware to interface the MAX31723 digital thermometer and thermostat to any system that utilizes PmodK-compatible expansion ports configurable for SPI and/or GPIO communication. The IC provides temperature-to-digital conversion with no additional components. 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 bits to 12bits. 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).
