Other Parts Discussed in Thread: LMG1020, CSD17571Q2, CSD15571Q2, CSD16301Q2

Dear sir ,

i want to create a signal from Arduino Due at 5MHZ (a square wave ) 50% duty cycle to be connected to fast gate controlled mosfet(NPN) to switch a load 12 volt 1 A

any recommendation about this NPN Mosfet. or updating for this idea like connecting a gate driver to Arduino for example , Please i need your recommendation

Thanks in advance ,

also if UCC2752X gate driver is suitable what MOSFET is recommended

Hi, George,

I would recommend LMG1020 or LMG1025 for your application.

As for a FET, let me ask my colleague to comment on that.
Best regards,

Don

Hello George,

Thanks for your interest in TI FETs. We have a few options for N-channel FETs. I would recommend CSD15571Q2, 20V in 2x2mm SON package. Some other alternatives would be CSD17571Q2, 30V FET in 2x2mm SON or CSD16301Q2 25V in the same package. The CSD16301Q2 has the lowest internal gate resistance and gate-drain charge which should yield fast switching required for this type of application. You may want to test a few different parts to see which gives you the best switching performance

Best Regards,

John Wallace
