Hi, i am currently building a smart charger circuit for a 12v lead acid car battery. i am using the uc3906 chip from the site (http://focus.ti.com/lit/ds/symlink/uc3906.pdf)
It may sound like a silly question but the resistor contained in the circuit `Rt' is it actually a resistor i require or is it simply a term for the total resistance of the circuit. I have used the design procedure to work out all the other values of components but am not totally sure about the Rt. Any feedback/ information would be greatly recieved as i am working to a deadline. Thanks
