W
PINTERNAL = IDD x VDD(1)
TH06
PI/O I/O Power Dissipation
â
W
PI/O = ï (IOL * VOL) + ï (IOH * (VDD - VOH))
TH07
PDER Derated Power
â
W
PDER = PDMAX (TJ - TA)/ï±JA(2)
Note 1: IDD is current to run the chip alone without driving any load on the output pins.
2: TA = Ambient Temperature
3: TJ = Junction Temperature
