Mouser now stocks the Diodes Inc. AP4370 decoding IC which is compatible
with the Qualcomm High Voltage Dedicated Charging Port (HVDCP) Quick Charge
(QC) 2.0 protocol.
Aimed at charger and adapter applications, the device decodes the different
combinations of D+/D - signals, generated by the portable device, into the
related configurations of V1/V2. This 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. It automatically provides 5V output configuration for
the connected portable device that is not compatible to Qualcomm QC 2.0
protocol. The AP4370 is packaged in TSOT26 and SOT26 packages.
