iW657P USB Power Delivery 3.0 Controller with Integrated Current Sense Supports Qualcomm Quick Charge 4+ 1 Description The iW657P is a USB Power Delivery (USB PD) interface controller which handles the communication between a Power Adapter and Mobile Device (MD). The controller enables the mobile device to alter the VBUS voltage from the default 5V and/or maximum current limitation (e.g. 3A) for higher power output or better efficiency. The iW657P supports USB PD 3.0, including Programmable Power Supply (PPS) support, while being backwards compatible with USB PD 2.0. The device also supports Qualcomm® Quick ChargeTM 4+ technology. The iW657P enables the use of advanced USB Type-CTM connector technology with CC1/CC2 pins for MD attach/detach detection and VCONN support for Electronically Marked Cable (EMC) rated current reading. The iW657P also integrates a high current charge-pump circuit to drive an external NFET VBUS disconnect switch. The iW657P resides on the secondary side of an AC/DC power supply and negotiates voltage and current settings with the primary-side controller, depending on the requests from the MD. The iW657P uses Dialog’s proprietary secondary-toprimary digital communication technology and when paired with one of Dialog’s primary-side RapidCharge™ controllers, such as the iW1781, iW1791 or iW1799, the iW657P eliminates the need for a discrete decoder on the primary side by using one optocoupler to transmit all necessary information for rapid charging to the primary side. This includes output voltage requests, output current limits, output voltage undershoot, output over-voltage, and fault and reset signals. The iW657P incorporates Dialog’s proven and reliable DLNK technology to communicate from the secondary to the primary and also has a built-in optocoupler LED driver to minimize the bill of material cost. The power supply designed with the iW657P is fully protected. Using over-voltage protection on the D+/D-/CC1/CC2 pins, the iW657P helps to address soft short issues in cables and connectors caused by poor or loose connections between the cable connector and the socket, contamination in the USB connector, or a worn out cable. Additionally, proprietary short circuit protection on the VBUS NFET ensures safe operation in the event of a short on the output, while the SD pin can be used with an external NTC resistor for protection from over-temeperature faults. The iW657P also integrates a secondary-side current sensing circuit that provides additional over-current protection for the power adapter. 2 Features ●● USB-IF PD certified: USB PD 3.0 + Programmable Power Supply (PPS) ●● ●● ●● ●● ●● ●● Proprietary VBUS NFET protection to protect VBUS switch from damage due to an output short circuit xx Maximum power limit in PPS to minimize power ●● Proprietary secondary-to-primary digital communication eliminates discrete decoders on the adapter size primary side and simplifies system designs xx Integrated CC transmitter/receiver supports BMC ●● D+/D-/CC1/CC2 over-voltage protection (OVP) address communication soft short issues in the output cables and connectors xx Backwards-compatible with USB PD 2.0 ●● Optional secondary-side current sensing circuit Supports Qualcomm Quick Charge 4+ Technology provides additional protection for over-load fault Supports up to 7 Power Data Objects (PDOs) ●● Uses external NTC for power adapter temperature sensing Supports wide output voltage range from 3.3 to 21V ●● Programmable active fast discharge from a high voltage VBUS level to 5V at MD unplug or upon Compatible with USB Type-C specification Rev 1.2 request with built-in switch or external switch for MD attach/detach detection and VCONN support for smart cables ●● Intelligent circuits helps achieve < 20mW system noload power at 5V steady-state operation.
