Asking for the NMOS design recommendation

Other Parts Discussed in Thread: CSD13202Q2, CSD17577Q3A, CSD17581Q3A

Hi Sir,


My customer would like design NMOS power MOS with conditions below.


  • The Rdson is better below 5mhom and VDS is 8V~10V.
  • Package is 2*2mm2


Would you please provide recommendation for this?





  • Hi Scott,

    Nice to hear from you again. Is this the same application we discussed previously on e2e and over regular email? We have a load switch FET selector tool available at the link below. The lowest rds(on) in 2x2mm SON is the CSD13202Q2 which is 7.5mOhm typical at VGS = 4.5V. In order to get to 5mOhm max, you will have to go to a larger 3x3mm SON package. Some possible devices are:

    • CSD17577Q3A, 4.8mOhm max at VGS = 10V
    • CSD17581Q3A, 4.7mOhm max at VGS = 4.5V
