Temperature Switch IC with S-5841 Series

The S-5841 Series is a temperature switch IC. The S-5841 Series has a built-in IC temperature sensor with the accuracy of ±2.5°C and detects the temperature. This IC restores the output voltage when the temperature drops to the level of release temperature. The S-5841 operates at the lower power supply voltage of 2.2 V and its current consumption is 10 µA Typ. due to CMOS configuration. A temperature sensor with the negative temperature coefficient, a reference voltage generation circuit and a comparator are integrated on one chip, and enclosed into the small packages SNT-6A and SOT-23-5.

Parts List

  • U(Ux), S and G at the end of the product name of ABLIC Inc. were used to indicate different material specifications as “environmental code”,
    however, these have now been unified into “lead-free and halogen-free” and are identical in terms of environmental quality.
  • Note: Lead-free plating other than 100% Sn is applied to some limited old products, therefore, please contact our sales representatives for details.
  • These descriptions may be different from the actual product name and parameter.
    Please confirm the product name and specifications with the data sheet again.
