Overview
MAX31722/MAX31723 Digital Thermometers and Thermostats with SPI/3-Wire Interface General Description The MAX31722/MAX31723 digital thermometers and thermostats with an SPI/3-wire interface provide temperature readings that indicate the device temperature.
No additional components are required; the devices are truly temperature-to-digital converters.
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 (TOUT).
Two thermostat operating modes, comparator and interrupt, control thermostat operation based on user-defined nonvolatile trip points (THIGH and TLOW).
Both devices feature a 1.
7V to 3.
7V supply rail.
