( ) derating curve in figure 32.(b) indicates power that can be c onsumed by ic with reference to ambient temperature. power that can be consumed by ic begins to attenuate at certain ambient temperature. this gradient is determined by thermal resistance ja. thermal resistance ja depends on chip size, power consumptio n, package, ambient te mperature, package condition, wind velocity, etc even when the same of package is used. thermal reduction curve indicates a reference value measured at a specified condition. figure 33.(c) show a derating curve for an example of tlr341g. when using the unit above ta=25 , subtract the value above per degree . permissible dissipation is the value when fr4 glass epoxy board 70mm 70mm 1.6mm (cooper foil area below 3%) is mounted 5.4 mw/ figure 33. derating curve tlr341g figure 32.thermal resistance and derating 0 50 75 100 125 150 25 p1 p2 pd (max) lsi M [w] ' ja2 ' ja1 tj ' (m ax ) ja2 < ja1 ?? ta [ ] ja2 ja1 tj (m ax ) ambient temperature power dissipation of lsi (b) derating curve a mbient temperature ta [ ] chip surface temperature tj[ ] package face temperature (a) thermal resistance ja=(tjmax-ta)/pd /w (c) tlr341g
