MAX31723PMB1 Peripheral Module
General Description
The MAX31723PMB1 peripheral module 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 tempera-
ture-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 appli-
cations 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 ther-
mal runaway conditions must be detected quickly. The
thermostat has a dedicated open-drain output (TOUT).
Two thermostat operating modes (comparator and inter-
rupt) control thermostat operation based on user-defined
nonvolatile trip points (T_HIGH and T_LOW).
Refer to the MAX31723 IC data sheet for detailed informa-
tion regarding operation of the IC.
