The MAX6514/MAX6515 low-cost, fully integrated temperature
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 temperature
sensor, and a comparator. They are available with factory-
trimmed temperature trip thresholds from -45°C to
+15°C and +35°C to +115°C in 10°C increments, and are
accurate to ±1°C (typ). These devices require no external
components and typically consume 22µA of supply current.
Hysteresis is pin selectable at 2°C or 10°C.
The MAX6514/MAX6515 are offered with hot-temperature
thresholds (+35°C to +115°C), asserting when the
temperature is above the threshold or with cold-temperature
thresholds (-45°C to +15°C), asserting when the
temperature is below the threshold. The MAX6514/MAX6515 can be used over a -35°C to +125°C range
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 MAX6514 has an active-high, push-pull output. The
MAX6515 has an active-low, open-drain output. These
devices are available in a space-saving 5-pin SOT23
package and operate over the -55°C to +125°C temperature
range.
