Qualcomm Quick Charge 3.0 Compatible Solution; companion to the iW636
The IW1782-00 is a high performance AC/DC power supply controller for rapid charge that uses digital control technology to build peak-current mode PWM flyback power supplies. The IW1782-00 is optimized to work with Dialog’s iW636 secondary-side controller for Qualcomm® Quick Charge™ 3.0 technology, to achieve fast and smooth voltage transition upon request by mobile devices (MD). When paired with the iW636, the IW1782-00 eliminates the discrete decoders on the primary side, minimizes the external component count and simplifies system designs. The iW636 can communicate with the IW1782-00 through one opto-coupler for all the necessary rapid charge information including output voltage requests, output current limits, output voltage undershoot and output over-voltage.
The IW1782-00 also incorporates Dialog’s SmartDefender™ smart hiccup technology to address soft short circuits in charger cables and connectors helping to prevent excessive heat build-up and damage. Learn more about SmartDefender smart hiccup technology here.
