POWER DE-RATING – SE Package
Power De -Rating
Due to internal power consumption, the temperature of the
IC (junction temperature, TJ) is higher than the ambient
environment temperature, TA. To ensure that the device
does not operate above the maximum rated junction
temperature use the following calculations:
∆T=PD × RθJA
Where PD = VCC × ICC
∴ ∆T = VCC × ICC × RθJA
Where ∆T denotes the temperature rise resulting from the
IC’s power dissipation:
TJ = TA + ∆T
RθJA = 77°C/W
T J(max) = 165°C
Typical T J Calculation:
TA = 25°C, VCC = 5 V, ICC(on) = 5.5 mA
PD = VCC × ICC
PD = 5 V × 5.5 mA = 27.5 mW
∆T = PD × RθJA = 27.5 mW × 77°C/W = 2.0°
TJ = TA + ∆T = 25°C + 2.0°C = 27.0°C
Maximum Allowable Power Dissipation Calculation
TJ = TA + ∆T
TJ(max) = 165°C, if TA = 150°C then:
165 = 150 + ∆T
∆T = 15°C
DT = PD× RθJA (RθJA = 77°C/W)
\ PD(max) = 15°C / 77°C/W = 195 mW @ TA = 150°C
Maximum V CC for PD(max) =111 mW at T A=150°C
PD = VCC × ICC ICC = 10mA (max) at 150°C
VCC = PD / ICC = 195 mW / 5.5 mA = 35.4 V
