TEST CONDITIONS
Maximum power consumption PMAX. = FIP driver dissipation + RL dissipation + LED driver dissipation + dynamic
power consumption
Where segment current = 3 mA, grid current = 15 mA, and LED current = 20 mA,
FIP driver dissipation = number of segments 6 + number of grids/(number of grids + 1) 30 (mW)
RL dissipation = (VDD VEE)2/50 (number of segments + 1) (mW)
LED driver dissipation = number of LEDs 20 (mW)
Dynamic power consumption = VDD 5 (mW)
Example
Where VEE = 25 V, VDD = 5 V, and in 16-segment and 6-digit modes,
FIP driver dissipation = 16 6 + 6/7 30 = 122
RL dissipation = 302/50 17 = 306
LED driver dissipation = 4 20 = 80
Dynamic power consumption = 5 5 = 25
