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.
