Technical Note
âFunction Diagramï¼ex. 80â detect ActiveâHâtype BDJ0801HFVï¼
Temperature sensor internal IC sense temperature, Vtemp terminal output voltage convert temperature.
Vtemp value is 1.300[V] at Ta = 30[â].
The value of Vtemp voltage reduce reversely proportional temperature at rate of â8.2mV/â.

If the temperature over detect temperature,

In case of OS return to âLâ,the temperature 10â lower than detect temperature.
