AP43771

The AP43771 is a highly integrated USB Type-C power delivery controller and targeted for USB-Type-C adapter and charger application. It is compatible with Qualcomm QC4/QC4+ protocol, which supports USB power delivery specification Rev3.0 V1.2 (including optional PPS support). The AP43771 can support PPS APDO (Augmented Power Data Object) with 20mV/step voltage resolution and 50mA/step current resolution for power management. What’s more, cable-loss compensation and SOP’ command for e-Marker detection are embedded too. The AP43771 can provide robust protection scheme with built-in OVP/OCP/SCP/OTP features. There are rich power functions embedded on the chip so as to reduce total BOM. A one-time–programmable ROM is provided for main firmware, and multi-time-programmable ROM is provided for user configuration data.

Evaluation report, including

1. the "ESTIMATED" process technology,
2. die size,
3. the "ESTIMATED" number of poly and metal layers
4. Die photos with low resolution

Evaluation only, the work scope of high-resolution chip imaging area and circuit analysis is opened to discussion

• If you decide to perform a circuit analysis, we will provide a complete delivery. including BrigenOne, EDIF format schematics, and PDF file
• The project is still in the "evaluation" phase, and the work scope is open to discussing.
• The information we provide about this project will be somewhat uncertain, as we have not yet performed high-resolution wafer images of each layer.
