EVM Description
The TPD4S214EVM provides full functionality of TPD4S214. Dependent on the jumper configurations,
VOTG_IN can be supplied through either the USB Type-A connector labeled USB_IN or the banana jack
labeled VOTG_IN. VBUS can be output to either the Micro USB-B connector labeled USB_OUT or a two
pin terminal block labeled VBUS_OUT. This configuration allows the device to be tested without the use of
expensive breakout boards; yet one or two breakout boards can still be accommodated. D+/D– lines can
only be characterized through the USB connectors.
Test points are provided for monitoring the DET, EN, and FLT logic pins.
VBUS current limiting adjustments are made by jumper selection of ADJ_SEL. R3 is left unpopulated to
allow for a custom user preferred value.
