Tool/software:
Hi Team,
My customer has a special application need your kindly support.
The LM74502 is acting as high-side switch to drive back to back MOSFET, the input is fix 12V while the output is battery. In customer application, they need to turn on the MOSFET before input 12V applying. Does LM74502 support external 15V power supply here? Means that VS is not connected to Vin but connect to external supply. From my understanding this is workable, but I don't know if any potential issues here, please help to review this architecture and provide guidance, thanks a lot.
Best Regards.
