    1.)    The bq51020 is a larger device with better thermal performance, lower thermal rise at 5W output.  Larger package and higher number of solder balls.

    2.)    The bq51020 is an adjustable output device from 4.5V to 8V.  The bq51013B is fixed at 5V out.

    3.)    Bq51013B has a QFN package option, preferred by some customers.

    4.)    Bq51021 will support I2C communications with a host controller,  (020 does not have I2C).
