MAX6516, MAX6517, MAX6518, MAX6519 Low-Cost, 2.7V To 5.5V, Analog Temperature Sensor Switches In A SOT23

The MAX6516 MAX6517 MAX6518 MAX6519 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 -45C to +115C in 10C increments, and are accurate to 0.5C (typ). These devices require no external components and typically consume 22A of supply current. Hysteresis is pin selectable at 2C or 10C.
The MAX6516 MAX6517 MAX6518 MAX6519 are offered with hot-temperature thresholds (+35C to +115C), asserting when the temperature is above the threshold, or with cold-temperature thresholds (-45C to +15C), 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 MAX6517 MAX6518 MAX6519 CAN be used over a range of -35C to +125C with a supply voltage of 2.7V to 5.5V. For applications sensing temperature down to -45C, 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 available in a space-saving 5-pin SOT23 package and operate over the -55C to +125C temperature range.
