TPS40057: Smart battery charger

PRABHAT RANJAN TRIPATHI

Part Number: TPS40057

I want to use PMP5306 for designing a smart battery charger for my battery pack.

But my charging current is 42 Amps at 16.8 Volts. Can you suggest modifications to the PMP5306 to achieve a higher charging current?

It will be also helpful if you can provide design files for PMP5306.

Thank you

    Hi,

    Please find related information including hardware schematic diagrams, software source code download link on the below:

    For TPS40057 part in the reference design, if you need to output a larger current you need to consider MOSFETs' rating and power dissipation for both MOSFETs and TPS40057. You can refer to 8.1.6 and 8.1.7 section on it's datasheet.

    Hey, Iven thanks for the reply.

    Thanks for pointing to the section 8.1.6 and 8.1.7.

    About the design files, the pdf does not have layout design guidelines and the schematic is not very clear, I was expecting Altium files.

    Thank you

    Hi,

    You can find the download link on ABSTRACT of the PDF content, also paste for you:

    .

    The schematic download is clear, BOM and gerber files are also included. These should be enough to build/assembly the reference design. Thanks.
