9.4 Calculating the Power Dissipation
The upper limit for power dissipation (PD) for the AS1100 is determined from the following equation:
PD = (V DD x 0.5mA) + (V DD - V LED )(DUTY x I SEG x N)
Where:
V DD = supply voltage
DUTY = duty cycle set by intensity register
N = number of segments driven (worst case is 8)
V LED = LED forward voltage
I SEG = segment current set by R SET
Dissipation Example:
I SEG = 40mA, N = 8, DUTY = 31/32, VLED = 1.8V at 40mA, V DD = 5.25V
PD = 5.25V(0.5mA) + (5.25V - 1.8V)(31/32 x 40mA x 8) = 1.07W
Thus, for a PDIP package θ JA = +75°C/W (from Table 13), the maximum allowed ambient temperature T A is given by:
T J,MAX = T A + PD x θ JA = 150°C = T A +1.07W x 75°C/W.
Where:
T A = +69.7°C.
The T A limit for SO Packages in the dissipation example above is +59.0°C.
