2.1 Power Requirements

For standalone PD evaluation, the main power supply for the TPS25751EVM is through the Type-C Sink only port (J2), which accepts 45W Type-C PD Source (15V to 20V). If the Type-C adapter is not capable of minimum 15V, then the TPS25751EVM does not power on properly. Alternatively, the EVM can also be powered on from an external bench supply connected to VSYS test point (TP19), with the bench supply providing 15V-20V range.

Note: VSYS (TP4) has an absolute maximum rating of 48V with recommended maximum of 42V. Applying more than the maximum voltage can cause damage to the EVM.

The TPS25751EVM can also be powered directly through Type-C Connector (J3) to simulate the TPS25751 in a dead battery scenario. When the TPS25751EVM is powered only through port J3, the EVM acts as sink only (unable to source unless VSYS is powered on).

For battery charging application, the selected BQ EVM can be used to power on the TPS25751EVM. The BQ25756EVM comes with a interfacing connector to connect to J7 connector on the TPS25751EVM. If a BQ Battery Charger is connected, the VBUS side of the BQ Battery Charger is connected to the internal high-voltage bidirectional power path (PPHV) of the TPS25751EVM. For more information on setting up and programming TPS25751 for battery charger application refer to Section 4.2.
