AP4370 Datasheet | Diodes Incorporated

DECODING IC PATIBLE TO QUALM QUICK CHARGE 2.0 PROTOCOL NEW PRODUCT Description The AP4370 is a decoding IC patible to Qualm High Voltage Dedicated Charging Port (HVDCP) Quick Charge (QC) 2.0 protocol. It decodes the different binations of D+/D- signals, generated by the portable device, into the related configurations of V1/V2, which can be used to change either voltage reference or voltage feedback divider resister for the controller IC to make the further constant voltage/constant current control. The AP4370 has over voltage discharge feature to accelerate output voltage decline transition. The AP4370 automatically provides 5V output configuration for the connected portable device that is not patible to Qualm QC 2.0 protocol. The AP4370 is packaged in SOT26 package.
