ECP5701 PD deception

Overview

ECP5701 PD Spoofing
1. Introduction

For more details, please refer to the datasheet
. 2. Testing
During testing, shorting different jumper cap positions will produce different voltages.
Note! Changing the jumper cap after powering on will not change the voltage; you need to unplug and replug the USB-C port for the change to take effect.
I used a Deuterium 65W charger with a Type-C 2 port for testing.
The specifications are as follows:

20V 3.25A

, 15V 3A

, 12V 3A,

9V 3A.

I also tested and verified a ZMI 65W GaN charger, but I won't include pictures here.
