The CYPD3125-40LQXIT: The wide supply tolerance also simplifies power routing in systems where the USB bus voltage is the primary rail.
40-QFN with exposed pad — rework considerations
The exposed pad helps dissipate heat from the Cortex-M0 core during active USB PD negotiation, but it also means the part is not hand-solderable without a hot-air station or reflow oven. The pad is large enough that a standard QFN rework profile works well — just pre-tin the pad and use a stencil for the perimeter pins to avoid bridging.
