ELECTRIC CHARACTERISTICS
( unless otherwised notice, Topr = -40 to 85 degree & Vcc = 3.0 to 5.5 V)
Note 4 : The derating function carries out the measurement in Ta= 25 degree not to work. The
specifications don't contain the dispersion of the R_Sens resistor. Io has the possibility to be different
from the specifications by the inductance value and the relations of the load.
Note 5 : It is a specifications guarantee by the design.
