General Description
The MAX6514/MAX6515 low-cost, fully integrated temper-
ature switches assert a logic signal when their die tem-
perature crosses a factory-programmed threshold.
Operating from a 2.7V to 5.5V supply, these devices fea-
ture a fixed voltage reference, an analog temperature
sensor, and a comparator. They are available with facto-
ry-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 22A of supply cur-
rent. Hysteresis is pin selectable at 2°C or 10°C.
The MAX6514/MAX6515 are offered with hot-tempera-
ture thresholds (+35°C to +115°C), asserting when the
temperature is above the threshold or with cold-temper-
ature 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 tem-
perature range.
