Hello All,

Greetings.

I am looking for gate driver to use to drive low side back to back connected MOSFET switch to disconnect the battery .

it needs to support common source or common drain configuration of MOSFET's  to disconnect the Battery rail in negative path.

Please suggest.

Thanks

Vasu

Hi Vasu,

You can use isolated power supply and connect its ground with Common source N_channel MOSFET. you can use this in low side , negative rail of the Battery.

Based on your MOSFET selection you can the  choose driver (N_channel low side MOSFET driver ).

Could you please share voltage and current rating ?

Regards,

Vignesh kumar.

Hi Vasu,

Thanks for contact Infineon community,

May I know if you have any specific reasons behind using Low side driver ?  We can arrive some discrete solution .

FYI - High side driver for back to back MOSFET - AUIR3242STR
