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)
Example
Where VEE = -25V, VDD = 5V, and in 16-segment and 6-digit modes,
FIP driver dissipation = 16 x 6 +6/7 x 30 = 122
RL dissipation = 30 2 /50 x 17 = 306
LED driver dissipation = 4 x 20 = 80
Dynamic power consumption = 5 x 5 = 25
