SN75477: BM2LB150FJ-CE2 replacement and does it have current limit function?

Part Number: SN75477

Tool/software:

Hello expert,

May I know if we can have replaced solution to replace BM2LB150FJ-CE2? It seems like SN75477 is okay to replace it based on cross reference tool in ti.com. May I know if it would be the solution? If yes, may I know if the IOK in datasheet as below is the current limit? 

Best regards,

Ann Lien

    Ann,

    We do not have a great replacement for BM2LB150FJ. The SN75477 was released in 1973 so support is going to be very limited. 

    Could you help us understand what the requirements of the system are? Would a normal load switch like TPS229950-Q1 work here? What are the nominal voltages, currents, etc. ?

    Best Regards,
    Tim

    Hello Timothy,

    Thanks for reply! Customer's requirement is current limit and it seems like if we don't have p2p solution then the change possibility will get lower. Thanks for your reply!

    Best regards,
