Dear Sir,
I am looking for a suitable Mosfet for the Load Switch application. Operating Voltage: 12V. Operating Current: 15A. Currently, I am using psmn4r8-100bse, Which is working fine but it is overrated.
Regards
Murthy

Hi Murthy,
We do not have an integrated device capable of handling 12V and 15A. I think you may have to use some sort of driver + external FET combination.
Hi Murthy,
Thanks for your interest in TI FETs.The device you're currently using is 100V, 4.8mOhm FET. For this application, I'd recommend a 25V or 30V FET. For about the same on resistance we have the CSD17581Q3A. It is a 30V device with 4.7mOhm max on resistance at VGS = 4.5V.
We have a load switch FET selection tool that you can use to compare different FETs for power loss, package and cost. I used it for this recommendation.
Thanks,
John Wallace
