General Description
The MAX6516–MAX6519 low-cost, fully integrated tem-
perature switches assert a logic signal when their die
temperature crosses a factory-programmed threshold.
Operating from a 2.7V to 5.5V supply, these devices
feature a fixed voltage reference, an analog tempera-
ture sensor, and a comparator. They are available with
factory-trimmed temperature trip thresholds from -45°C
to +115°C in 10°C increments, and are accurate to
±0.5°C (typ). These devices require no external compo-
nents and typically consume 22µA of supply current.
Hysteresis is pin selectable at 2°C or 10°C.
The MAX6516–MAX6519 are offered with hot-tempera-
ture thresholds (+35°C to +115°C), asserting when the
temperature is above the threshold, or with cold-tem-
perature thresholds (-45°C to +15°C), asserting when
the temperature is below the threshold.
These devices provide an analog output proportional to
temperature and are stable with any capacitive load up
to 1000pF. The MAX6516–MAX6519 can be used over a
range of -35°C to +125°C with a supply voltage of 2.7V
to 5.5V. For applications sensing temperature down to
-45°C, a supply voltage above 4.5V is required.
The MAX6516 and MAX6518 have an active-high,
push-pull output. The MAX6517 and MAX6519 have an
active-low, open-drain output. These devices are avail-
able in a space-saving 5-pin SOT23 package and oper-
ate over the -55°C to +125°C temperature range.
