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.

General Description

Applications

♦ High-Accuracy ±1.5°C (max) over -15°C to +65°C

♦ Low-Power Consumption: 22µA Typical Current

♦ Factory-Programmed Thresholds from -45°C to

♦ Open-Drain or Push-Pull Outputs

♦ Pin-Selectable 2°C or 10°C Hysteresis

Note: These parts are offered in 16 standard temperature ver-

sions with a minimum order of 2500 pieces. To complete the

suffix information, add P or N for positive or negative trip tem-

perature, and select an available trip point in degrees centi-

grade. For example, the MAX6514UKP065+T describes a

MAX6514 in a 5-pin SOT23 package with a +65°C threshold in

tape and reel (2.5k minimum order). Contact the factory for

pricing and availability.
