Hi All.
I am doing a project which is a Li-Po (Single Cell, 6000mA) Powered ARM CPU based device. It have USB-C receptacle and SD Card. The CPU have USB 2.0 and USB 3.0 both in OTG. This device mainly feature:
-# File transfer between PC (USB 2.0 or 3.0) and Board's SD card (USB Device Mode)
-# File transfer between SD card (USB 2.0 or 3.0) and any USB 2.0 or 3.0 Storage Device like Portable HDD/SSD or PenDrive etc (USB Host Mode)
-# Charge the Board Li-Po via USB-C 5V, 3A (15W)
My ques is mainly on the Charging circuit. For my application do I need to implement USB-C Power Delivery circuit to enable the Li-Po charging from a USB-C PD Charger? If a non PD system connects to a PD Charger or MacBok Pro then can it get 5V 3A by default without PD negotiation?
Thanks in advance.
Regards.
