Other Parts Discussed in Thread: BQ25731, USB-PD-CHG-EVM-01, , BQ25792, TPS25750, BQ25731EVM
Hello, I am using tps25750S and bq25731 chips to try and create a pcb with usb-c power out capabilities.
Using Altium I have wired up the tps25750s chip and based the design off the USB-PD-CHG-EVM-01 Unfortunately this device uses a different bq chip that seems to Vary by quite a bit.
The TPS25750EVM uses the bq25731 so I wanted to know if there were cad/altium files available for this device as it would greatly increase my understanding of how to wire the systems. if not are there any suggested documents to look through to get the two chips connected and working? The plan is to currently use the schematics in the tps25750EVM datasheet, but they are not that easy to follow.
Additionally, I have a question about if we wired the tps25750s correctly.
does pin 19 (vsys) connect to A1,b1,d1 and e1, which are also connected to the output of the bq chip? where as a2,b2,d2,e2 go to pins 26 and 27 as well as the usb-c itself.
