Description

The AP43771V is a highly integrated USB Type-C ® power delivery controller targeted for USB Type-C adapter and charger application. It is compatible with Qualcomm® QC4/4+/QC5 protocol, which supports USB power delivery specification Rev3.1 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.

Dedicated part number AP43771VFBZ-13-FR01 (W-DFN3030-14 (Type A1)) with standard firmware provides a preloaded 8-powerprofile menu. System manufacturers could easily select a desired power profile (Constant Voltage CV and Constant Current CC) through a single resistor attached to the relevant pin (OTP pin) to meet output power requirements of a USB PD charger or adaptor.

Supporting emerging multiple Type-C PD applications, the AP43771V (W-QFN4040-24 (Type A1)) with customized firmware can be used for implementing smart power sharing scheme. It monitors status of other I2C interface connected ports and leverages the embedded MCU for command execution through I2C interface to re-allocate desired power profile for each Type-C port.
