Other Parts Discussed in Thread: LM74502-Q1, LM74800-Q1, LM74720-Q1

Whether LM74700-Q1 could support Hot-Plug?

If not, whether we have other product which could support hot-plug?

Hi Fabio,

What is the operating range?

Do you wish to limit inrush current?

It is used in the 12V battery. Sure, the hot plug means there will be high di/dt and dv/dt.

Hi Fabio,

LM74700 cannot control inrush current, we need a blocking FET also for it.

Please consider back-to-back FET controllers like

LM74502-q1: reverse polarity protector only

LM74800-q1: Reverse current blocking and reverse polarity protector

LM74720-q1: Similar to LM74800-q1 but lower Iq.
