INA300-Q1: Some questions

Part Number: INA300-Q1
Other Parts Discussed in Thread: INA300

Hi team,

I have some questions here.

1. My customer is using INA300 for BCM application but based on cost they don't want to add bidirectional operation. I would like to know that what kind of situation we should need to add bidirectional operation? or just recommend to do that. Would you please give me some example?

2.Would we have any development about Integrated eFuse?

3.As I know that the max current we can detect is based on Rshunt's design and efuse's detect range. Of course if we want to detect high current will have more loss on Rshunt. Just would like to know that what's the highest current you've ever done in a real situation?

BR,

Jimmy

    Hi Jimmy,
    1. If there is a possibility that the current may reverse direction, ie, it can flow either forward or backward, then bidirectional functionality is probably required. At least it should be evaluated. A typical application is motor drive in blow partial BCM block diagram, where most of the time if not always, bidirectionality is required.


    2. As you may know, TI offers a portfolio of eFuse. You can check it out on the web. There is no such development within current sensing line of products.
    3. It is impossible to know all customer applications, so our perspective on this may not be complete. But 2-3 hundred amps is not unheard of.
