Maximum power consumption PMAX. = FIP driver dissipation + RL dissipation + LED driver dissipation +
dynamic power consumption
Where segment current = 3mA, grid current = 15mA, and LED current = 20mA,
FIP driver dissipation = number of segments x 6 + number of grids/ (number of grids + 1) x 30(mW)
RL dissipation = (VDD-VEE) 2 /50 x (number of segments + 1) (mW)
LED driver dissipation = number of LEDs x 20(mW)
Dynamic power consumption = VDD x 5(mW)
