US 11,112,844 B2 · Universal serial bus (USB) type-C and power delivery port with scalable power architecture

Abstract

A Universal Serial Bus (USB) Type-C and power delivery port with scalable power architecture is disclosed. In one aspect, at least two circuits for a USB port are consolidated into a single integrated circuit (IC). At least one of the at least two circuits is part of a Type-C port controller (TCPC) group of circuits including sensors associated with detecting whether a voltage and current are present at pins of a USB receptacle. At least the other one of the at least two circuits is selected from a battery-related group of circuits including a battery charging circuit, an over-voltage protection circuit, and a conditioning circuit. The more circuitry integrated into the single IC the more readily scalable the end product is for a multi-port device. Additional circuitry such as a light emitting diode (LED) driver may also be included in the single IC.
