9.2.2.1 Typical Supply Current Equations

(Calculated based on room temperature and typical Silicon process)

ISO7640FM:

At VCC1 = VCC2 = 3.3 V

ICC1 = 0.388 + 0.0312 × f

(1)

ICC2 = 3.39 + 0.03561 × f + 0.006588 × f × CL

(2)

At VCC1 = VCC2 = 5 V

ICC1 = 0.584 + 0.05349 × f

(3)

ICC2 = 4.184 + 0.05597 × f + 0.009771 × f × CL

(4)

ISO7641FM:

At VCC1 = VCC2 = 3.3 V

ICC1 = 1.848 + 0.03233 × f + 0.001645 × f × CL

(5)

ICC2 = 3.005 + 0.03459 x f + 0.0049395 × f × CL

(6)

At VCC1 = VCC2 = 5 V

ICC1 = 2.369 + 0.05385 × f + 0.002448 × f × CL

(7)

ICC2 = 3.857 + 0.05506 × f + 0.007348 × f × CL

(8)

ICC1 and ICC2 are typical supply currents measured in mA; f is data rate measured in Mbps; CL is the capacitive

load on each channel measured in pF.
