Diodes Incorporated introduced the AP43770 USB Type-C power delivery (PD) controller, a highly-integrated solution to implement PD over USB in devices and offline power adapters. The AP43770 features an embedded microcontroller running firmware compliant with the latest USB Type-C specification, and USB PD Revision 3.0 V1.1. Support for Qualcomm Quick Charge (QC) 4/4+ is built into the device, as well as QC3.0, QC2.0, and Battery Charging (BC) revision 1.2 and other legacy protocols with auto-detection.

The programmable power supply (PPS) feature is also supported by the AP43770, and allows the output voltage to vary based on the load requirements. Support for PPS is implemented with a constant current and constant voltage output driver that is adjustable in 50mA steps up to 6A, and 20mV steps between 3V and 20V, respectively. The AP43770 supports eMarker technology, to detect and identify cables before power is delivered, and cable compensation is also supported.

The AP43770 also features up to 8kb of OTP (for main firmware code) or MTP (for user configurable parameters). MTP memory can be used to set up power specification and protocol options to the manufacturer's requirements. The AP43770 is available in the TSSOP-16 package and priced at $1.35 each in 1,000 piece quantities.
