AP53782

 USB PD Solutions Webinar

Description

The AP53782 is a highly integrated USB Type-C ® PD3.1 Dual-Role Power (DRP) controller to support Extended Power Range (EPR)/ Adjustable Voltage Supply (AVS) up to 28V and Standard Power Range (SPR)/Programmable Power Supply (PPS) up to 21V.

The AP53782 is targeting for operating with external MCU through the I2C Interface pins (SCL, SDA) and interrupt mechanism. With the I2C registers and commands defined by AP53782, the host MCU could control the AP53782 to act as a sink controller to get desired Request Data Object (RDO) from a PD3.1 compliant source adapter, or to play as a source PD controller to provide Power Data Object (PDO) capability to supply a Type-C connector-equipped device (TCD).

The AP53782 could consume as low as 50µA to meet requirement of equipped battery-power devices during the power down mode. The AP53782 supports the QC2.0/3.0 functions and dead battery during the sink role and provides both I2C control and VFB feedback for the external DC/DC controller during the power negotiation. Meanwhile, the host MCU could further inquire about the status of various I2C registers for intended applications. The AP53782 integrates Rp/Rd termination resistors and switches for DRP control. It operates from 3.6V up to 28V with low-side current sense topology.

Based on high-voltage process, the AP53782 offers short-protection between CC1/CC2 (CCx) pins to adjacent high-voltage pin up to 34V. The smart built-in firmware of the AP53782 offers comprehensive safety protection schemes, including overvoltage protection (OVP), undervoltage protection (UVP), overcurrent protection (OCP), and moisture detection for the USB connector.
