MAX6516 - Analog Temperature Sensor Switches

General Description

The MAX6516

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.

Key Features

  • High Accuracy ±1.5°C (max) Over -15°C to +65°C Temperature Range.
  • Low Power Consumption.
  • 22µA Typical Current.
  • Factory-Programmed Thresholds from -45°C to +115°C in 10°C Increments.
  • Analog Output to Allow Board-Level Testing.
  • Open-Drain or Push-Pull Outputs.
  • Pin-Selectable 2°C or 10°C Hysteresis Ordering Information PART TEMP RANGE PIN-.

19-3007; Rev 1; 2/11 MAX6516–MAX6519 Low-Cost, 2.7V to 5.5V, Analog Temperature Sensor Switches in a SOT23 General Description The MAX6516–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 -45°C to +115°C in 10°C increments, and are accurate to ±0.5°C (typ). These devices require no external components and typically consume 22µA of supply current. Hysteresis is pin selectable at 2°C or 10°C.
