LM7480-Q1: Control Multiple back to back MOSFETS with single controller

arif khan

Part Number: LM7480-Q1

Tool/software:

I want to know if a "single" LM7480-Q1 ideal diode controller can control multiple back to back MOSFETS (parallel sets for increased current capacity)? Thanks.

Hi Arif,

Yes LM7480-Q1 can do so.

Shiven,

Just to clarify me application. I will use one LM7480-Q1 to turn on-off 4 back to back MOSFET ideal diodes which are in parallel.

Hi Arif,

Parallel FETs can be driven as shown.

Here each rectangle represents a MOSFET.

DG stands for DGATE.

HG stands for HGATE.
