LM5064EVK: Hot swap controller

Part Number: LM5064EVK
Other Parts Discussed in Thread: LM5064, TPS2662, LM5067

Hi, I am designing hot swap controller  to connect to the back panel of our system.

My requirements are Vmin=-15.075v, Vmax=-14.925v, Vtyp=-15v at 150ma current limit. which eval board or IC should i use for this.

I tried looking at LM5064 eval board but it doesn't support -15V it's out of range but the IC data sheet from -10V to -40V

Is there a single Eval board or IC that can handle both +ve and -ve voltages. My requirements for the system is

1. Vtyp= 5.0v ; Vmin = 4.975v; Vmax= 5.025v at 80ma current limit

2.  Vtyp= +15v ; Vmin = 14.925v; Vmax= 15.075v at 150ma current limit

3.  Vtyp= -15v ; Vmin = -15.075v; Vmax= -14.925v at 150ma current limit

I need under voltage, over voltage and current limit protection for the device.

Please can you suggest and eval board or IC that can be used for the above spec.

Looking forward for your reply.

Thank you.

  • Hi S M,

    Welcome to E2E!

    We have to use separate devices for +ve, -ve rails. Here are my suggestions.

    1. Vtyp= 5.0v ; Vmin = 4.975v; Vmax= 5.025v at 80ma current limit

    TPS2662

    2.  Vtyp= +15v ; Vmin = 14.925v; Vmax= 15.075v at 150ma current limit

    TPS2662

    3.  Vtyp= -15v ; Vmin = -15.075v; Vmax= -14.925v at 150ma current limit

    LM5067

    Best Regards, Rakesh
