AM Classification
SLUS745A – NOVEMBER 2006 – REVISED MAY 2007
AUTO MODE FUNCTIONAL DESCRIPTION (continued)
After a successful discovery of a valid PD the TPS23841 enters the classification function that identifies the
power level based on the PD's current signature. The classification current level is measured at a reduced
terminal voltage of 17.5V. During classification the power dissipation can be at its highest; therefore, to prevent
over temperature shutdown in automode only one port classifies at a time. When multiple ports successfully
discover and proceed to classification at the same time the auto sequencer processes each request separately
allowing only one port to enter classification. Figure 3 shows all 4 ports successfully detecting a valid PD at the
same time and than the classification of each port occurring separately.
