Hi,
I am using TPS25833-Q1
I did Rsns value is equal to the 0.015 ohm and therefore, Rlim value is 26.1kohm. According to this value, I get the current that I wanted to set. (which is 1.5A). However the datasheet say that Vsns should be 50mV.
According to my design, Vsns value is 22,5mV. (1.5A x 0.015ohm)
If I change Rsns value to 0.033ohm, I get Vsns equal to 50mV however I have to change the Rlim value to get 1.5A. (should change 26.1k to 12kohm.) ( you can find the equation in the attachment.)
My question is that really necessary to Vsns value equal to 50mV? or 0.0225V value is also OK? The reason I asked this is, I dont want to change my layout alot.
Regards,
Mehmet
