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 22µA 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.
