Description
General part information
iW1781 Series
The iW1781 is a 45W output, high-performance AC/DC RapidCharge™ power supply controller that supports USB Power Delivery 3.0 (USB PD 3.0) and other rapid charging protocols.
It is optimized to work with Renesas'iW657PUSB PD interface controller in mobile device adapters to achieve fast and smooth voltage transition on request from the mobile device. The iW657P accepts fast charging protocols, including USB PD 3.0. It transmits all necessary information via an optocoupler to the iW1781, including voltage requests, output current limits, output voltage undershoot, output overvoltage, and fault and reset signals.
A full array of protection features includes Renesas'SmartDefender™advanced hiccup technology to address soft short circuits in charger cables and connectors, helping to prevent excessive heat build-up and damage.
