BTN8982TA Current calculation

Jump to solution

I am using BTN8982TA IC. In that IC, i am getting voltage as 1.93 in IS pin, and i am using Rs  as 3.6K.

How to calculate IL load current by using these values?

How to find the dkilis value?

Re: BTN8982TA Current calculation

Hi,

   We can calculate il and dkilis as follows,

 

ils = Vis/Ris  = 1.93/3.6x10^3 = 0.5361 x 10^-3 = 0.5361mA.

 

dkilis = 1/ils = 1865.3236

 

Load current = il = dkilis * ( ils - isoffset)

   = 0.6828 A

 

 

Regards,

Abhilash P
