Part Number: BQ25896

Hi Team,

 

Customer would like to try support OTG 2A.

Can you help provide a template for OTG 2A?

Or which registers we have to do the configuration?

Thanks,

SHH

    Hi SHH,

    If you follow steps 1-5 from the datasheet excerpt you included (OTG_CONFIG bit is REG03 bit 5) , you then need to set the boost current limit bits REG0A [0:2] to 110.  You can also change the voltage regulation from the default of 4.998V to 4.55V - 5.51V in REG0A.
