AP43671

Description

The DIODES™ AP43671 is a highly integrated and intelligent USB Type-C power delivery (PD) controller with an embedded synchronous rectification (SR) controller. It is ideally targeted for cost-performance-sensitive USB Type-C adaptors and charger applications.

The device supports USB PD3. 0 V1.2, and Programmable Power Supply (PPS) and Qualcomm QC4/QC4+ protocols. Leveraging its embedded MCU and supporting circuitry, the AP43671 can accommodate popular quick-charging protocols for firmware stored in One-Time-Programmable (OTP) memory.

To enable optimal system BOM and performance implementation of quick chargers, the AP43671 embeds a multiple-mode adaptive SR controller where its key performance and safety parameters can be fine-tuned by a built-in MCU.

The AP43671 also adopts a relatively small current-sensing resistor (5mΩ) that is used to provide accurate current measurements without sacrificing power consumption.

The AP43671 provides robust protection schemes, which includes a CC1/CC2 short protection against VBUS (up to 24V) as well as built-in OVP/OCP/SCP/OTP features to provide necessary safety protection.
