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.
