Guide to Selecting Connections for Remote Power Supply
Sensing
To assure consistency of input power levels, some applications use a practice of connecting the remote sense signal input of an
on-board power supply to one of power supply pins of the IC device. The advantage of using this connection is the ability to
compensate for the slow components of the IR drop caused by resistive supply current path from on-board power supply to the
pins layer on the package. However, because of specific device requirements, not every ball connection can be selected as the
remote sense pin. Some of these pins must be connected to the appropriate power supply or ground to ensure correct device
functionality. Some connections supply critical power to a specific high usage area of the IC die; using such a connection as a
non-supply pin could impact necessary supply current during high current events. The following balls can be used as the board
supply remote sense output without degrading the power and ground supply quality:
VDD: W10, T19
VSS: J18, Y10
M3VDD: None
Do not use any other connections for remote sensing. Use of any other connections for this purpose can result in application and
device failure.
