BDJ□□□1HFV Series
Technical Note
●Function Diagram(ex. 80℃ detect Active“H”type BDJ0801HFV)
Temperature sensor internal IC sense temperature, Vtemp terminal output voltage convert temperature.
Vtemp value is 1.300[V] at Ta = 30[℃].
The value of Vtemp voltage reduce reversely proportional temperature at rate of –8.2mV/℃.

If the temperature over detect temperature,
internal comparator operate OS output “L” to “H”.(ex.active “H” Type)
In case of OS return to “L”,the temperature 10℃ lower than detect temperature.
