POWER CONSIDERATIONS

This section provides information on power dissipation and junction temperature for the ICS853054.

Equations and example calculations are also provided.

1. Power Dissipation.

The total power dissipation for the ICS853054 is the sum of the core power plus the power dissipated in the load(s).

The following is the power dissipation for V_CC= 3.3V 5% = 3.465V, which gives worst case results.

NOTE: Please refer to Section 3 for details on calculating power dissipated in the load.

•

Power (core)_MAX= V_{CC_MAX}* I_{EE_MAX}= 3.465V * 61mA = 211.37mW

Power (outputs)_MAX= 27.83mW/Loaded Output pair

Total Power_{_MAX}(3.465V, with all outputs switching) = 211.37mW + 27.83mW = 239.2mW

2. Junction Temperature.

Junction temperature, Tj, is the temperature at the junction of the bond wire and bond pad and directly affects the reliability of the

device.The maximum recommended junction temperature for HiPerClockS^TMdevices is 125°C.

The equation for Tj is as follows: Tj = θ_JA* Pd_total + T_A

Tj = JunctionTemperature

θ_JA= junction-to-AmbientThermal Resistance

Pd_total =Total Device Power Dissipation (example calculation is in section 1 above)

T_A= AmbientTemperature

In order to calculate junction temperature, the appropriate junction-to-ambient thermal resistance θ_JAmust be used. Assuming a

moderate air flow of 200 meters per second and a multi-layer board, the appropriate value is 81.8°C/W perTable 6 below.

Therefore, Tj for an ambient temperature of 85°C with all outputs switching is:

85°C + 0.239W * 81.8°C/W = 104.6°C. This is well below the limit of 125°C.

This calculation is only an example.Tj will obviously vary depending on the number of loaded outputs, supply voltage, air flow,

and the type of board (single layer or multi-layer).
