Digital Thermometers and Thermostats
with SPI/3-Wire Interface
19-5629; Rev 0; 11/10
General Description
The MAX31722/MAX31723 digital thermometers and
thermostats with an SPI"/3-wire interface provide tem-
perature 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 ther-
mostat operation based on user-defined nonvolatile trip
points (T
HIGH
and T
LOW
). Both devices feature a 1.7V to
3.7V supply rail.
