Diodes Incorporated AP43771H Enhanced USB PD 3.1 Protocol Controller

Diodes Incorporated AP43771H Enhanced USB PD 3.1 Protocol Controller is a highly integrated USB Type-C™ power delivery (PD) controller targeted for premium USB Type-C adapter/charger applications. The device supports USB power delivery specification Rev 3.1 V1.6 Extended Power Range (EPR) 28V, including AVS capability of 100mV/Step support. AP43771H is a pin-to-pin upgrade part from the AP43771V [W-DFN3030-14 (Type A1)]. The enhancements of AP43771H over the AP43771V include efficiency improvement with a Rsense 5mΩ option and an enlarged 1.5KB SRAM size. Furthermore, the AP43771H implements a CC1/CC2-short-to-VBUS protection up to 34V. To address higher output voltage and power requirements, AP43771H supports PD3.1 up to 28V VBUS output with AVS capability (100mV/step).
