Cn0352 is used as mulichannel battery management application.
Hi, can you please elaborate on the question?
If you can please help....In the reference design of Multichannel Li-ion battery testing system(CN0352), ADP5065 is used which gives battery charge current rating of 2A but I want the battery charge current rating as 4A....what replacement should I do
There are many options. Is charging at 4A the only difference or will any other parts of the circuit change (input voltage, battery voltage, etc)?
What battery chemistry are you planning on using? And what charge voltage?
Here's a parametric search of all of our 4A switching battery chargers for now, I can help you to narrow this down with a little more information:

Thank you Zack. Actually we are trying to test Li-ion batteries with 0-5V, 4A rating.And I found CN0352 reference design very usefulexcept the component ADP5065 has current sensing range of 0-2A only. So, I want to increase it to 4A.@
hi ad4sensify: unfortunately the ADP5065 haven't the 4A version for now, for the 4A Switching Battery Chargers please check Selection Table for Switching Battery Chargers | Parametric Search | Analog Devices
Ok, thank you for the info. I've narrowed down the search:
I think from here you can just try to choose the simplest solution.
LT3651-4.1 or LT3651-4.2 may be a good choice for you here. These are not drop-in replacements for ADP5065, so you may need to tweak the circuit a bit, but it shouldn't be too much work.
I will try this solution. Thanx for your prompt support.
I am still searching for another option to use instead of ADP5065. As I told earlier, we are testing Li-ion batteries with rating 0-5V, 4A. Actually LT3651-4.1 or LT3651-4.2 are matching with the current requirement. But how can I observe various battery performance characteristics as we can in the CN0352 reference design. Can I get more detailed help on this please?Reference Circuits
What are you looking for exactly? Can you point me to the performance characteristics you are referencing?
Demo boards are available for LT3651: DC1362A-A for 4.2V, DC1362A-B for 4.1V.
If you are looking for advanced monitoring of the battery, take a look at LTC4015. However, this part is significantly more complex.
Just providing you some more details about the system I am working on:
The Li-ion battery(0-5V, 4A) performance characteristics
5.Loop time charge/ discharge efficiency curve
I want to incorporate these characteristics in my battery monitoring system.
Thanks and regards,
We have a part similar to the LTC4015 with the switching FETs integrated, but it can only charge up to 3.2A. If this is still of interest to you, let me know and I can send you more information.
I will go through the suggestions u gave and let u know it very soon.
Thank you so much.
