2.4 Header Information

The J2 and J5 headers are setup for ease of use with 5V and 10V level logic analyzers. The most pertinent signals and power rails for testing the TPS26750 are pulled out to these headers. If utilizing the Liquid Detection feature, note that pins SBU1 and SBU2 on Header J5 are not the SBU signals directly at the DUT Type-C connecter (J4), but are instead the SBU signals from the Liquid Detection circuit to the SBUx pins of the TPD4S480, as shown in Figure 5-2.

14 HV_SYS_D10 (HV_SYS divided by 11)
15 VBUS_D10 (VBUS divided by 11) (labeled as VBUS_LV_D10 on silk screen)
16 PPHV__D10 (PPHV divided by 11)
17 VBUS_LV_D10 (VBUS_LV divide by 11) (labeled as VBUS_D10 on silk screen)
18 No Connect
19 GND
20 GND
Note: The label suffix _D10 implies that the signal has been divided by 10. However, the actual value that the original signal has been divided by is 11; that is, if VBUS measures 48V, then VBUS_D10 measures approximately 4.36V.
