BDJxxx1HFV Series
Application Information
1. Function Diagram (ex. 80°C detect Active–H type BDJ0801HFV)
The internal IC temperature sensor senses temperature. TEMP terminal output voltage is converted to temperature.
VTEMP value is 1.300[V] at Ta = 30[°C].
The value of VTEMP voltage reduction is inversely proportional to the temperature at a rate of -8.2mV/°C.

If the temperature exceeds the detect point temperature, the internal comparator forces the OS output to change from
“L” to “H”. (ex. Active-H Type)
OS returns to “L” when the temperature becomes 10°C lower than the detect point temperature.
