First question asked
I want to make a 15A constant current source. I hope you can recommend the relevant circuit.Specific requirements are as follows:

1. sinking current to ground, Lithium battery discharge (29V) ,15A current.

2.current fixed

3.Current accuracy within 5%.

4.output:Lithium battery 29V, MAX30V

5.transistor:used MOS IRF540 before, but cannot reach 15A。

If you have a better recommendation circuit or better information,I would appreciate it。What should I pay attention to in the design?

Thank you !

Hello,

Thank you for posting on Infineon Community.

Regarding your query, can you please tell me for what application you want to design a current source so that I can recommend you a MOSFET as per the application qualification?
Also, please use this link for finding Infineon products :https://www.infineon.com/cms/en/tools/ 

Thanks and Regards,
