AP43771V
AP43771V is HIGH-PERFORMANCE USB PD CONTROLLER manufactured by Diodes Incorporated.
HIGH-PERFORMANCE USB PD CONTROLLER
Description
The DIODES AP43771V is a highly integrated USB Type-C® power delivery controller targeted for USB Type-C adapter and charger application. It is patible with Qualm® 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 20m V/step voltage resolution and 50m A/step current resolution for power management. Also embedded is cable-loss pensation and SOP mand 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 status of other I2C interface connected ports and leverages the embedded MCU for mand execution through I2C interface to re-allocate desired power profile for each Type C port.
