Thank Simon!

This makes perfect sense now, thank you very much for clarifying!

Thank you,

Ted

Hi again Ted

Sorry, I got this wrong the first time around and have first of all updated my last answer to question 2, which was misunderstood on my part. As for the discharge current limit. This is programmable via the BCHGISETDISCHARGEMSB and BCHGISETDISCHARGELSB registers which is why the current limit specification is so wide.

I hope this clears things up a bit. Sorry about the misunderstanding.

Best regards,

Simon

Hello,

Thank you for that, however, I believe this is a different parameter. I am asking about the Discharge current limit, as opposed to the Charge current limit:

Thank you,

This is a mistake in the product specification, and I have reported it to our designers now. You can use the following formulas to find the actual charge current limits here (section 6.2.4 in the PS):

And yes, they will be affected by the temperature, but not a lot by the PCB layout I believe Correction. No, there is very little power dissipation, and it is not thermally limited by package/PCB design. It is directly linked to the RONcharger specification.

Best regards,

Simon

Hi Ted

I have asked one of our PMIC designers about advice on this and will get back to you as soon as I hear from them.

Best regards,

Simon
