2.7 Configuring the TPS25730EVM
The TPS25730EVM provides device status information of the TPS25730 using LEDs that correspond to GPIO
events of the TPS25730. Each LED has the corresponding event printed to the left when the TPS25730EVM is
oriented with TPS25730EVM readable.
Table 2-4. LED Indicator Events
GPIO Event Description Conditions for LED on
SINK_EN Indicates when PPHV is enabled. Can be used for GPIO control of
an external power path.
PPHV is disabled.
PLUG_FLIP Indicates the orientation of the USB-C plug. Plug is upside-down.
DBG_ACC Indicates whether or not a debug accessory is connected. Debug accessory is connected.
PLUG_EVENT Indicates a connection to a source device via a USB-C plug. The LED turns on when
connected.
CAP_MIS Indicates a mismatch in capabilities between the connected source
and the TPS25730.
The LED blinks when a
capabilities mismatch occurs.
Each switch set must have only one of the eight switches in the on position, for a total of four switches in the
ON position for a successful configuration. The table below shows which ADCIN pin configures which setting.
Please note that ADCIN3 and ADCIN4 together determine operating current and maximum current based on the
combination of the two inputs. ADCIN3 alone does not directly map to operating current and ADCIN4 does not
map directly to maximum current.

ADCIN2 Maximum voltage

Each labeled switch number on the TPS25730EVM switch sets corresponds to an ADCIN decoded value, shown
in the table below.
