The iW656 USB Power Delivery (USB PD) interface controller resides on the secondary side of the AC/DC power supply and manages the communication between the power adapter and mobile device.
The iW656 works with Renesas' iW1781 or iW1791 RapidCharge™ primary-side controller and accepts fast charging protocols, including USB PD. It transmits all necessary information via an optocoupler to the primary side, including voltage requests, output current limits, output voltage undershoot, output overvoltage, and fault and reset signals.
The iW656 also works with Renesas' iW676 synchronous rectifier, which eliminates the need for a parallel Schottky diode for higher efficiency and lower BOM cost.
For USB PD 3.0 and Qualcomm Quick Charge 4+ applications, see the iW656P or iW657P.
