The integrated USB Type-C® PD and charging reference design for 2-4 cell batteries is a 2-in-1, USB Type-C and PD controller along with a battery charging system. This reference design can support charging 2S to 4S batteries through a USB Type-C port, in addition to the standard USB Type-C communication, power delivery negotiations, power role swaps, and data role swaps. This board features charging current up to 5 A, without the need for any external FETs enabling a much smaller design size, reducing total BOM cost, and so on. In addition, an external microprocessor is not necessary as the USB-PD controller can handle the I²C communication to the battery charger integrated circuit (IC). As a result, there is no need for any firmware development work and the design greatly reduces the total time needed to market.
