6.3.4 EPR Adapter

The TPD4S480 integrates additional circuitry that may be used to adapt a PD controller with pin tolerances below EPR levels for use in EPR applications. The EPR adapter consists of two components, the VBUS divider and the EPR blocking FET gate driver. The EPR adapter features are enabled by asserting the EPR_EN pin or when the VBUS pin exceeds EPR_THRESH_R.
