LTC3350 MOSFET IC Availability

Hi,

I am using LTC3350  part number: LTC3350EUHF#TRPBF in one of my project for back-up power, the back-up voltage is about 10V.

But in one of the boards we have shortage of Mosfet i.e. M2 and M3(part number:BSZ060NE2LSATMA1 recommended in the design).

 we checked there no availability of this Mosfet in online(mouser and Digikey).

So is it possible for us to use the mosfet recommended for M1(part number:SIS438DN-T1-GE3) in the circuit to be used for M2 and M3. 

Or is there any alternate part number for this part : BSZ060NE2LSATMA1  .

Kindly help us in solving this issue.

regards,

Bhavi

  • The SiS438DN-T3-GE3 can be used for M2 an M3 instead of the BSZ060NE2LSATMA1. We do not have a specific secondary part replacement for this part. Please also see the Power MOSFET selection section on page 28 of the datasheet for selecting MOSFETs and making sure that there is not too much power dissipation in them for your application. Please also look at the Top MOSFET driver supply and INTVCC/DRVCC sections on page 29 of the datasheet to make sure the boost circuit is sized correctly and there is not too much power dissipation in the IC.
