● Calculation of power consumption by IC
Power consumption of this IC is approximately calculated as follows:
Pc=Pc1+Pc2+Pc3
? Pc1 ： Power consumption by circuit current
Pc1=Vcc × Icc
? Pc2 ： Power consumption on output stage
Pc2=VOL × Io
VOL is the L voltage of output terminal 1 and 2.
Io is the current flowing to output terminal 1 and 2.
? Pc3 ： Power consumption at FG and AL
Pc3=VFG × IFG ＋ VAL × IAL
VFG is L voltage of FG output.

VAL is L voltage of AL output.
IFG and IAL are the current of FG and AL.
Fig.20 Calculation of power consumption by IC
Power consumption by IC greatly changes with use condition of IC such as power supply voltage and output current.
Consider thermal design so that the maximum power dissipation on IC package is not exceeded.
