BQ25886: Review schematic and some question

Sean Heo

Part Number: BQ25886

Dear Sir,

Related to BQ25886, I have tested BQ25886 EVM, and some question about drawing schematic.

Please review my schematic and let me know problem.

1. Input currnet: I want to connect 1A D+/D-. How can I connect D+/D- ?

==> Refer to Input current limit setting from D+/D- detection, input current is 1A if DIVIDER 3 choose, how can I connect D+/D- ?

2. Review my schematic, and let me know wrong point.

Thank you.

    Sean,

     

    1. If you wish to force the D+/D- detection into Divider 3, you must apply 2.0V on D+ and 2.7 V on D-. I suggest you do this by having a resistor divider from a reference voltage to GND. This reference voltage can be created from an LDO tied to SYS or BAT similar to the EVM schematic.
    2. I cannot see all of your schematic from the screenshot. Please send me the complete schematic and I will take a look.

     

    Thanks,

    Ricardo
