Other Parts Discussed in Thread: BQ25890H, BQ25898D

Dear TI:
Please help to check does BQ25895 support QC protocol?

If BQ25895 support QC, how does it communicate with the input adapter or other equipment?

Does QC protocol handshake need special communication interface?

Thanks!

Regards!

Hey Eric,

The BQ25895 High Voltage DCP handshaking feature is compatible with protocols QC2.0. For QC3.0 and above, you will need chargers like the following below and some associated firmware.

BQ25890H

BQ25898D

For the firmware, consider this software reference design that can be modified for the QC protocol: Optimizing Efficiency by Handshaking Adjustable Adapters and Battery Chargers Reference Design

As far as what is needed for the QC protocol, I recommend looking at the specification from Qual Comm.

Joel H
