TYPICAL SUPPLY CURRENT EQUATIONS

(Calculated based on room temperature and typical Silicon process)

ISO7631FM:

At VCC1 = VCC2 = 3.3V

ICC1 = 1.8072 + 0.0244 x f + 0.0016 x f x CL

ICC2 = 2.4625 + 0.0252 x f + 0.0033 x f x CL

At VCC1 = VCC2 = 5V

ICC1 = 2.3183 + 0.04 x f + 0.0025 x f x CL

ICC2 = 3.2582 + 0.0403 x f + 0.0049 x f x CL

ISO7631FC:

At VCC1 = VCC2 = 3.3V

ICC1 = 1.1762 + 0.0325 x f + 0.0017 x f x CL

ICC2 = 1.5285 + 0.0299 x f + 0.0033 x f x CL

At VCC1 = VCC2 = 5V

ICC1 = 1.6001 + 0.0528 x f + 0.0025 x f x CL

ICC2 = 2.2032 + 0.0475 x f + 0.005 x f x CL

ISO7640FC:

At VCC1 = VCC2 = 3.3V

ICC1 = 0.3209 + 0.0488 x f

ICC2 = 1.9699 + 0.0385 x f + 0.0066 x f x CL

At VCC1 = VCC2 = 5V

ICC1 = 0.5038 + 0.0812 x f

ICC2 = 2.6117 + 0.0603 x f + 0.0101 x f x CL

ISO7641FC:

At VCC1 = VCC2 = 3.3V

ICC1 = 1.2162 + 0.0462 x f + 0.0017 x f x CL

ICC2 = 1.8054 + 0.0411 x f + 0.005 x f x CL

At VCC1 = VCC2 = 5V

ICC1 = 1.6583 + 0.0757 x f + 0.0025 x f x CL

ICC2 = 2.5008 + 0.0655 x f + 0.0076 x f x CL

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.
