Voltage Power Sequencing Options
To meet the 375 mA inrush current requirements (not including external capacitors) the ramp time
should be 5 ms -100 ms on all power rails. For faster ramps (100 us - 5 ms), expect higher inrush
current due to the high charging current of the decoupling capacitors of 3.3 V, 1.8 V and 1.0 V rails.
5.3 Thermal Information
The 82575EB device is specified for operation when the ambient temperature (TA) is within the range of
0 °C to 55 °C. For information about the thermal characteristics of the device, including operation
outside this range, please refer to the 82575EB Thermal Application Note.
