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.
