General Description
The MAX1755/MAX1756 are temperature monitors with
±3°C accuracy, each with a built-in comparator and
SMBus-controlled variable trip threshold. This DAC-
programmable threshold allows specific thermal zones
and system responses to overtemperature conditions to
be adjusted under software control. The MAX1755/
MAX1756 feature serial programmability, low cost, wide
supply-voltage range, and a tiny package.
The MAX1755 has a self-clearing thermostat output
(
OVERT
), and the MAX1756 has a latched interrupt out-
put (
ALERT
). A variety of slave addresses allow for up
to six devices per system (Table 3).
The MAX1755 has 4°C of built-in hysteresis. The
MAX1756 detects both low-to-high and high-to-low tem-
perature transitions within an 8°C temperature window.
This arrangement supports “windowing” algorithms
where the comparison threshold is reprogrammed “on-
the-fly.”
The MAX1755/MAX1756 are offered in the 6-pin SOT23
package and are specified over the -40°C to +125°C
temperature range. For other temperature sensors with
SMBus interfaces, refer to the MAX1617, MAX1618,
MAX1668, and MAX1805 data sheets.
