(b) indicates the power that the ic can consume with reference to ambient temperature. power consumption of the ic begins to attenuate at certai n temperatures. this gradient is determined by thermal resistance ( ja), which depends on the chip size, power consumpti on, package, ambient temperature, package condition, wind velocity, etc. this may also vary even when the sa me of package is used. thermal reduction curve indicates a reference value measured at a specified condition. figure 49.
