over operating free-air temperature range (unless otherwise noted)(1)
MIN MAX UNIT
Supply voltage V33D to DVSS 0 4 V
V33A to AVSS 0 4 V
Input voltage on all I/O pins except PMBUS_CNTRL, PMBALERT, MARGIN19, and MARGIN20, regardless of whether the device is powered(2) –0.3 5.5 V
PMBUS_CNTRL, PMBALERT, MARGIN19, and MARGIN20 –0.3 VV33D + 0.3 V
Output current Maximum current per output pin 25 mA
Operating junction temperature, TJ TBD 150 °C
Storage temperature, Tstg –65 150 °C
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those listed in the Recommended Operating Conditions table. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) Applies to static and dynamic signals including overshoot.
