iW662 Product details

Description

The iW662 is an AC/DC secondary-side combo controller for Qualcomm® Quick ChargeTM 3.0 (QC3.0) which includes USB interface, secondary-to-primary communication and synchronous rectification functions in a single IC.

Features

XM-Comm proprietary secondary-to-primary digital communication transmits all information for rapid charge without an optocoupler: output voltage requests, output current limits, output voltage undershoot, over-voltage protection, and other fault and reset signals.
Lossless MOSFET VDS sensing for SR timing control with digital adaptive turn-off control.
Optimized 5V MOSFET gate driver.
High-voltage drain sensing up to 100V with no additional external clamp.
