I plan to build a 20 amp constant current sink circuit to test out 3.6 volt batteries. The pass elements will be 4, CSD18534KCS mosfets that are driven into the linear region. The gate resistors I plan to use are 4, 100 ohms resistors connected to output of the TL431. My question is, will these mosfets cause the TL431 to oscillate?? And if so, how would I stop this?
