PD Power Dissipation

—

W

PD = PINTERNAL + PI/O

TH05 PINTERNAL Internal Power Dissipation

—

W

PINTERNAL = IDD x VDD(1)

TH06

PI/O I/O Power Dissipation

—

W

PI/O =  (IOL * VOL) +  (IOH * (VDD - VOH))

TH07

PDER Derated Power

—

W

PDER = PDMAX (TJ - TA)/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
