AP43771V

HIGH-PERFORMANCE USB PD CONTROLLER

Description

The AP43771V is a highly integrated USB Type-C® power delivery

controller

targeted

for

USB

Type-C

adapters

and

charger

applications. It is compatible with Qualcomm® QC4/4+/QC5 protocol,

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

(including optional PPS support).

The AP43771V can support PPS APDO (Augmented Power Data

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

resolution for power management. Also embedded is cable-loss

compensation and SOP command for e-Marker detection.

The AP43771V can provide a robust protection scheme with built-in

OVP/OCP/SCP/OTP features.

Supporting emerging multiple Type-C PD applications, the AP43771V

(W-QFN4040-24 (Type A1)) can be used for implementing smart

power-sharing scheme. It monitors the status of other I2C interface

connected ports and leverages the embedded MCU for command

execution through I2C interface to re-allocate the desired power

profile for each Type-C port.

Rich power functions are embedded on the chip to reduce total BOM.

A one-time-programmable ROM is provided for main firmware, and a

multi-time-programmable ROM is provided for user-configuration

data.
