Digital temperature indicators protect USB power delivery systems from overheating. The devices do this by exponentially increasing their resistance and reducing the flow of current when the temperature of a USB charging circuit rises above a set point. The setPTM digital temperature indicators made by Littelfuse are optimized to protect USB Type-C plugs with captive cables while handling the heaviest USB-PD loads.
- Operate in a resistance range of 500 mΩ to 12 Ω
- Maximum hold current of 60 mA or 75 mA
- Trip current of 250 mA or 300 mA
- Maximum voltage rating of 6 V
- ELV compliant
- Certified lead-free, halogen-free, and RoHS compliant
- Eliminating the need to convert analog temperature data to digital outputs increases accuracy and efficiency
- Compact design (2.2x2.0x0.6 mm maximum)
- Zero voltage (IR) loss from resistors
- Compatible with reflow soldering processes
