Hello Sarabh,

Thanks for your interest in this part. I have few questions about this.

What's your input voltage and charging voltage?

Do you have any input current limits and will you be charging from a USB adapter?

Best Regards,

Hello Saurabh,

I think the BQ25756E would work well for your application.

If you are using a USB 100W adaptor, you can use the TPS25751 to set and request the USB power contracts. If you use the BQ25756E EVM with the TPS25751EVM, you'll need to make sure to use a 5mΩ input sense resistor.
