Figure 18. Hdc At 25 °C And Junction-Temperature-Dependent Dissipated Power For Stm32H7; Figure 19. Hdc At 85 °C And Junction-Temperature-Dependent Dissipated Power For Stm32H7 - ST STM32 Application Note

Figure 18.
Once the HDC of the design is defined (by measurement at 25 °C), and assuming that this HDC is constant at
25°C and 85 °C, the operating point of the design at 85 °C is given by translating the HDC at 85 °C as shown in
the figure and table below.
