Product Details

The MAX31723PMB1 peripheral module provides the necessary hardware to interface the MAX31723 digital thermometer and thermostat to any system that utilizes Pmod™-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 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 T_OUT). Two thermostat operating modes (comparator and interrupt) control thermostat operation based on user-defined nonvolatile trip points (T_HIGH and T_LOW).

Refer to the MAX31723 IC data sheet for detailed information regarding operation of the IC.
