Description

The AP43771 is a highly integrated USB Type-C power delivery

controller and targeted for USB-Type-C adapter and charger

application. It is compatible with Qualcomm QC4/QC4+ protocol,

which supports USB power delivery specification Rev3.0 V1.2

including optional PPS support).

The AP43771 can support PPS APDO (Augmented Power Data

Object) with 20mV/step voltage resolution and 50mA/step current

resolution for power management. What’s more, cable-loss

compensation and SOP’ command for e-Marker detection are

embedded too.

The AP43771 can provide robust protection scheme with built-in

OVP/OCP/SCP/OTP features.

There are rich power functions embedded on the chip so as to reduce

total BOM. A one-time–programmable ROM is provided for main

firmware, and multi-time-programmable ROM is provided for user

configuration data.
