TMP390 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 . The trip temperatures (TTRIP) and thermal hysteresis (THYST) options are programmed by two E96-series resistors (1% tolerance) on...
TMP390 Key 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 from 0°C to +70°C)
- A3 Level: ±3.5°C (±2.0°C from 0°C to +70°C)
- Ultra-low power consumption: 0.5 µA typical at 25°C
