TMP390 - Resistor-Programmable Temperature Switch

Datasheet Summary

Description

The TMP390 device is part of a family of ultra-low power, dual channel, resistor programmable temperature switches that enable protection and detection of system thermal events from

50°C to 130°C.

The TMP390 offers independent overtemperature (hot) and undertemperature (cold) detection .

Features

  • Resistor programmable temperature trip points and hysteresis options.
  • Resistor tolerances contribute zero error.
  • Hysteresis options: 5°C, 10°C and 20°C.
  • Separate outputs for overtemperature or undertemperature detection.
  • Channel A (overtemperature): +30 to +124°C, 2°C steps.
  • Channel B (undertemperature):.
  • 50 to +25°C, 5°C steps.
  • Accuracy level options (maximum at.
  • 55°C to +130°C):.
  • A2 Level: ±3.0°C (±1.5°C.
