BQ27546-G1: Using UART to communicate HDQ interface data to BQ27546 or BQ25742

Hugo Lee

Part Number: BQ27546-G1

Dear Sir,

We plan to use UART to communicate HDQ interface data to BQ27546 or BQ25742 as slua408a mentioned.

Is it doable for BQ27546 or BQ25742?

Could you share "UART to HDQ reference schematic" with schematic and eBOM included for us to follow up the design?

Thanks.

Hello Hugo,

This is something you will need to develop yourself. We do not have a UART to HDQ. You can perhaps look at one-wire open source material online.

Hi Kang,

Would you share the link about the material online?

Thanks.
