Diodes Incorporated introduces the AP43771V, a dedicated USB Type-C power delivery PD3.0 PPS decoder designed specifically for power source applications with legacy capabilities. This decoder complies with USB Type-C specification rev.1.2 and USB power delivery (PD) specification rev. 3.0 V1.1, guaranteeing compatibility and adherence to industry standards.
The AP43771V has obtained USB PD3.0 PPS silicon compliance certification (TID - 4305), ensuring its performance and quality. It also passes the QC4/4+/QC5 compliance certification by Granite River Labs (GRL), further validating its reliability.
With support for PPS APDO (Augmented Power Data Object), the AP43771V offers precise control over voltage and current levels. It provides 20 mV/step resolution for voltage adjustment and 50 mA/step resolution for current adjustment, allowing for fine-tuned power delivery and optimal battery thermal management.
To compensate for cable loss and maintain accurate power delivery, the AP43771V includes cable-loss compensation functionality. This ensures that the charger can deliver the intended power even when faced with cable resistance or length limitations, maximizing charging efficiency.
The device also features SOP (Structured Vendor-defined Message) command support for e-Marker detection. This allows the charger to identify connected devices and adjust power delivery accordingly, ensuring efficient and safe charging.
The AP43771V offers an I2C interface and GPIO pins for easy integration into various applications. These interfaces enable seamless communication with the decoder and provide flexibility for system designers during implementation.
For applications requiring multiple-port independent output voltage, the AP43771V includes built-in smart power-sharing firmware. This firmware maximizes power usage in any scenario by intelligently distributing power among multiple ports, ensuring optimal charging performance.
To simplify the design process, Diodes' AP43771V provides reference designs for 45 W and 65 W single-C or dual-C USB PD3.0 PPS-based quick chargers. These reference designs help shorten the design-to-production cycle time, allowing manufacturers to bring chargers to market more efficiently.
The AP43771V is available in W-DFN3030-14 and W-QFN4040-24 package types, providing options for different application requirements and board sizes. With its constant-current mode protection and comprehensive features, the AP43771V from Diodes Incorporated offers a reliable and efficient solution for charger applications.
