DECODING IC COMPATIBLE TO QUALCOMM QUICK CHARGE 2.0 PROTOCOL
Description
The AP4370 is a decoding IC compatible to Qualcomm High Voltage
Dedicated Charging Port (HVDCP) Quick Charge (QC) 2.0 protocol.
It decodes the different combinations 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 compatible to Qualcomm QC
2.0 protocol.
The AP4370 is packaged in TSOT26 and SOT26 packages.
