Computing Power Dissipation
Determine the MAX6958/MAX6959 upper-limit power
dissipation (P D ) with the following equation:
P D = (V+ ? I+) + (V+ - V LED ) (DUTY ? I SEG ? N)
For a 16-pin DIP package (T JA = 1/0.0105 = +95.2°C/W
from Absolute Maximum Ratings ), the maximum
allowed ambient temperature T A is given by:
T J(MAX) = T A + (P D ? T JA ) = +150°C
= T A + (0.652 ? 95.2°C/W)
where:
V+ = supply voltage
I+ = operating supply current
DUTY = duty cycle set by intensity register
N = number of segments driven (worst case is nine)
V LED = LED forward voltage at I SEG
I SEG = peak segment current
P D = power dissipation, in mW if currents are in mA
Therefore, T A = +87.9°C.
Power Supplies
The MAX6958/MAX6959 operate from a single 3V to
5.5V power supply. Bypass V+ with a 0.1μF capacitor
to GND, as close to the device as possible. Bypass V+
with an additional 10μF capacitor if the MAX6958/
MAX6959 are not close to the board input ’s bulk
decoupling capacitor.
Dissipation example:
Chip Information
I SEG = 23mA, N = 9, DUTY = 63/64, V LED = 2.2V,
V+ = 5.25V
P D = 5.25V (5.9mA) + (5.25V - 2.2V)
(63/64 ? 23mA ? 9) = 0.652W
