DRV8834 – About accuracy of ITRIP

$

0

Hi Team,

 

Our customer are evaluating DRV8834 at the following condition.

Could you please let me ask the following question?

 

----------------------

[condition]

-VREF=0.7V

-RISENSE = 0.47Ω

-ITRIP = VREF/(5*RISENSE) ≒ 0.298A

-----------

 

[Question]

Does an error of ITRIP occur when we use the same DRV8834(the same individual) repeatedly?

So, is the accuracy of ITRIP “0.298A +/- 〇〇%” ?

 

*In this case, it isn’t necessary to add an error of VREF and RISENSE (the outside factor).

 My customer would like to know the factor of itself.

 

Currently, they are concerned the following comment.

 

 

----------------------

 

Regards,

Kanemaru
