Other Parts Discussed in Thread: TPS65987, TPS25751, TPS25751EVM
I'm designing an USB-PD souce for up to 100W (5V/3A, 9V/3A, 15V/3A and 20V/3A always and 20V/5A if cable is e-marked and cable’s capabilities allow 5A). It must work stand-alone, i.e. without external microcontroller and/or firmware development
Does TPS65987D support cable identification by reading out e-markers automatically? What we need is that the chip itself identifies the cables current carrying capability and advertises the suitable power delivery object, i.e. 20V/5A if allowed by the cable or 20V/3A otherwise. And is it also possible to configure a GPIO either to detect an overcurrent event or to control a DC/DC-converters output current limit?
