USB Type-C controller with dual supply for power delivery
The Texas Instruments TPS25750DRJKR is a USB Type-C controller designed to handle power delivery negotiation and cable orientation detection in a 38-PowerWFQFN package. It accepts a dual supply range of 3V to 3.6V and 4.9V to 5.5V, allowing it to work from both a 3.3V system rail and a 5V USB bus.
Supply rails and current budget for the BOM
Maximum supply current is 315 mA, which sets the thermal budget for the 38-WQFN (4x6) package and the upstream regulator sizing. The dual supply input means the controller can draw from a 3.3V standby rail or the 5V VBUS — useful in designs where the system must negotiate power before the main rail is up.
