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.

ADCIN1 Minimum voltage
ADCIN2 Maximum voltage
ADCIN3 & ADCIN4 Operating current and maximum current

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